I'll throw in my comments on this as well, for what it's worth (which, as I'm very well aware, my opinion and $5 will get me a cup of coffee at Starbucks):
I've got a Monoprice Mini v1. $200, and I had to make some VERY minor tweaks out of the box to be able to print on it (mostly just bed leveling, which got shifted during shipping; 4 screws on the bed were turned with a sheet of paper between the hotend and the bed, following instructions, and it printed just fine). It's a great little printer for the price, and I can print ABS and PLA on it (although I haven't tried ABS yet).
It prints fairly cleanly, although it DOES print slow; it's just one of those facts of life I've come to accept if I want a good, strong part. The biggest complaint I have with it is the limited print bed size - I was hoping to be able to print out iPhone cases, but I can't print out anything for the iPhone 6 or newer since they're bigger than my print bed. That said, I've done control horns a plenty, motor mounts for various planes, interlocking bases for my Lego Dimensions characters, antenna mounts for my drone, a dice tower for my parents (it's a little tower that has levels inside it that, when you drop the dice inside, it tumbles them down and around so that they essentially "roll" the dice for you; it's great when you're playing a board game that takes up an entire table and you have very little space to actually roll dice)...It's a great little printer.
If you want to do 3D printed planes or drone frames, though? You're going to need a bigger print bed - and the cost will go up with that. I'm going to side with jhitesma on the Prusa i3 MK2S, as my father bought one and has been using it since early June. He's printed a Spitfire (still building it), Teenage Mutant Ninja Turtles planters for succulents, a phone case for his iPhone 7, servo extension locks, control horns, a firewall for a Versa Wing, a fidget spinner for my mom...Last I talked with him, he was planning on designing and printing out a new bevel cutter for foam board, since the ones he's seen on Thingiverse don't work the way he wants them to (He's a former engineer for General Dynamics/Martin Murrieta/Lockheed Martin/ULA and worked with CAD for most of his life, so he's kinda obsessed with making it better LOL). The i3 MK2S has a lot of versatility, and one of the latest things that he's drooling over is the Multi-Material upgrade that they offer for it, allowing him to print different colors from 4 different spools, or even use a water soluble material for supports and another material, like ABS or PLA, so that he can dunk it in water and have the supports fall away.
The downside is that the $700 price tag (and that's if you assemble it yourself; it really isn't hard, to be honest) keeps some people away, but for the size of the print bed and what the printer can do, it's a price tag you can't beat. I've looked at others with similar bed sizes, and they were almost all $1000+, or were "prosumer" or low end business class printers that had catches with them - for example, proprietary spools that required you to purchase your printing materials from the company. Honestly, the best bang for your buck is the Prusa i3 - however, their turnaround times are a little on the slow side because there's been such a huge demand for them. Josef Prusa has been getting them out as quickly as he can (and he is a REALLY cool guy; I met him at the Bay Area Maker Faire in May, and he was really happy to demo the products for me and explain everything. I had no idea that I was talking to the head of the company at the time; I thought it was just one of the tech specialists. It was only after I saw his picture on the Prusa website that I realized who I was talking to!)
