I've got the Attitude V4's, and I'm really happy with them. The standard Fatshark module it comes with is "meh", but it's good enough until you need to make the jump to diversity, in which case, $80 for a True-D diversity module, which is pretty much plug n' play, will work nicely.
Now, just a question - have you thought about the box monitor style headsets, like the Quanum Cyclops V2? HobbyKing has them on sale right now for $44. I'll be the first to admit that they're not as compact as a set of Fatsharks or Aomways, but the picture is really good on them, you can use a 2S-3S battery with either the round connector like the Fatshark batteries use, or a 2S battery w/the red JST plug, or a 3S battery with XT60/EC3 connectors, as it comes with adapter cables for those types of batteries.
It does not have a DVR or diversity like the Fatsharks, but they're a great first headset. I flew them for almost a year, and I still have them; they've been relegated to my backup headset for people who are wanting to go for a ride along.

The scan button works great, plus has the ability to change up and down on channels. I'll admit that they're not the best goggles ever, but at $44 for a set, they're a helluva price point...
