the new gopro black is pretty good to be honest. having said that, I've got myself a Sony Nex 5 recemtly for use with my hex on a gimbal - it's DSLR quality, interchangeable lenses etc compact but small enough to fly. you can get a second hand one off ebay within your budget. Have a think about what lens you want to get with it. If you want to spend a bit more you can get a nex 7 but to be honest the nex 5 does the job and you can get it a lot cheaper. hope that helps. there may be better advice out there but as far as i know the nex 5 is the benchmark for dslr quality in a small flyable package.
