LOL welcome to the flite test family.
Just a word of warning with those little LRP drones - they're tiny. As in, "Fit in the palm of your hand" tiny. I had one just like it that I sorta kinda learned to fly, until I ran out of props due to crashing and couldn't fly it anymore. When I was flying it, it would drop out of the sky and end up underneath things, like the sofa, or the large, heavy coffee table with drawers.
The one big problem I found with these is that they're not really much like flying a bigger quad, and you CANNOT fly them outdoors; any sort of wind whatsoever pushes them exactly where you DON'T want them to go, like onto a neighbor's roof, over the fence where a large dog with pointy teeth lives, or into your wife's rosebushes that have tons of thorns.
I would recommend, when you can afford to take the hit, get into something bigger, like an Inductrix FPV BL or Torrent, Newbeedrone Acrobee, or FliteTest Gremlin. These options will still be smaller, but will give you the ability to fly with a real transmitter, as opposed to the smaller "toy" transmitters that are meant for someone with hands only slightly larger than a toddler's.
In addition, you'll be able to get external battery packs, AND run FPV with the aforementioned models.
The transmitter required for any of those options would also give you the ability to fly planes, whether you build them from a FliteTest kit/foamboard, or purchased a "bind n' fly" from say, Horizon Hobbies, so that's something to consider as well. I understand the cost may be a factor at first; you'll be looking at around $300-$350 for the transmitter, a quadcopter like the Acrobee, battery, charger, and an inexpensive FPV headset like the Quanum Cyclops, but the plus is that you can then take the transmitter to another vehicle, the charger (if you get one that allows you to charge lipo/LiHV batteries with different connections), and FPV headset will be reusable for other vehicles you may build, so you won't have to put out the additional expenses for those items, saving you some money in the long run.
Here's an example (and keep in mind this is just a recommendation, some of these can be swapped out for other equipment if you want something different/i.e., better, or even a little cheaper depending on what you pick):
Newbeedrone Acrobee Basic Kit: $99.99
Spektrum DXe transmitter: $69.99
Hitec RDX1 Pro AC/DC battery charger: $74.99
Quanum Cyclops Diversity Headset: $99.87
250 mAh Lipo batteries for Acrobee: 4 for $20
This is just a suggestion, but this is a good way to start. The Acrobee will give you full flight capabilities, allow you to learn Betaflight tuning capabilities for the drones (which will be useful if you ever move into the racing drone world), and it has additional parts that are cheap, should you break a frame, need replacement motors or upgrades, or want additional props.
The Spektrum DXe radio is the cheapest DSMX radio you can buy. It has the ability to be used for multiple different models, but it has to be programmed via a smartphone app, which can be a little clunky. However, it will allow you to fly 6 channel planes as well as quads, so it's a cheap radio that you can work with if you want DSMX protocol, AND use it for E-Flite bind n' fly planes. There ARE other protocols that you can use Are there other, better, options? Yes, but they are either more expensive, have a steep learning curve to the software, or a manual that was originally written in Chinese and then poorly translated to English.
The Hitec charger - there are other options; this is my personal pick due to size (it's compact and fits nicely into a backpack, doesn't have a wide footprint when you are charging on a table, and fits into an ammo box that doubles as my toolbox and charger for bigger batteries, in case they go up in flames), has a USB charging port (I can use it to charge my cell phone or other USB devices if I need) AND it is AC/DC compatible, which allows me to charge off the wall power at home, connect to the solar power system at the field, or even charge off of my car battery if I'm flying somewhere that they don't have a charging station. There ARE cheaper options; however, some require a power supply from an old computer, or are exclusively DC power. If you're going to get a battery charger, I HIGHLY recommend that you get a charger that is AC/DC. The cost is well worth it, regardless of which brand you pick, simply because of the flexibility it offers.
The Quanum Cyclops Diversity headset is one of the best CHEAP headsets for the buck. It offers diversity antennas (this means it will switch between the strongest signal depending on which antenna is closer or more direct line of sight), and it has a digital video recorder built in to record your flights. It will also fit over glasses, if you are vision impaired like I am. Are there better ones? Yes. I also own a pair of Fatshark Attitude V4 goggles, which are lighter, smaller, and make me look like Geordi Laforge from Star Trek: The Next Generation when I'm wearing them. They're also $400 for a pair, and if you're on a budget, most likely out of your price range. The Quanums are a great starter pair, and should you get some extra money and want to buy the Fatsharks (which are pretty much the gold standard for FPV flight) the Quanums make for a great backup pair for someone who wants to do a "ride along" while you're flying (say, for example, your kids want to see what it's like).
Lastly, the batteries. The prices for the batteries vary depending on what you go with. The batteries required for the Acrobee are 1S (or 1 cell, series batteries) that CAN, in theory, be used with other aircraft, but are usually relegated to ultra micro or UMX models due to weight. Can you find them cheaper? Sure. Amazon has several sets of 6 for $20. I don't recommend buying the cheapest batteries that you can find on Amazon, though - I did, and had them puff up and one of them actually explode due to my charging method. Also, cheaper batteries tend to have lower mAh, lower flight times, and the cheaper JST connections that don't necessarily match with the NewBeeDrone's connector, which is a JST-PH 2.0 connection, and far superior to the 1.0, which has a tendency to fail after 30 or so uses.
Sorry for the long post, but I figure this gives you some info to look up and compare with. Again, these are simply recommendations for equipment; they may change with time, as newer equipment may replace older models, or something superior comes out. You may even find something better that does the job - but these recommendations are a better quality than what you'll find in the toy aisles at Walmart, Best Buy, or Fry's Electronics, and will give you a chance to branch out if you decide that quadcopters aren't really your thing. Maybe you find you're wanting to fly sailplanes, or warbirds, or helicopters; a good portion of this equipment can move with you, and save you some initial startup costs of the switch.
