I really want a Naza-H Bill, but to be honest I will be investing in FPV gear before I make that purchase.
I'm not just ready quite yet to make the leap, but when I do I am pretty sure I will get Fat Shark Dominator goggles and to start I'm thinking 5.8 Ghz video transmitter and receiver. From what I've seen this frequency gets me enough range for what I want to do right away. After I get some experience with that then I am still interested in long range but to do that it's not just the FPV video I will also need a new long range control signal system and I don't know yet which of those I like best. However after I get 5.8 Ghz FPV and before I go long range I think a waypoint enabled flight controller is higher on my list and for that I'm leaning towards the 3DR APM system.
Man, they just keep coming up with cool stuff. What's the RC hobby going to look like in another few years. I think I would be interested an audio telemetry system that are just beginning to come out. You have an ear bud to hear things like elevation and battery pack voltage instead of having to look down at the TX display to see what's going on that many now have. http://www.wireless-copilot.com/safe2fly.aspx
I know! The UAV field is dwarfing the computer field in research and development. Very exciting times indeed. Speaking of audio telemetry, already happening in the APM project. You have to listen carefully because it was not the focus on the demonstration, but watch this video and maybe turn up the volume a bit to hear the guys Archos tablet talking. http://southernoregonrc.com/index.php?topic=3271.0
