Also check out the V2 Predator RTF package on HK, which has your goggles (built in vrx), 250mW vtx, lc filter and camera. You can get SpiroNET antennas from there too, giving you more video range than your stock 9x has.
Having the whole ground station in your head set is lovely. Plug in and fly. Mine's so quick to set up that I'm often left waiting for the gps lock before I can fly. With the upgraded antennas, your whole system is set up with goggles for a shade over $300...
But then I wouldn't (though some would) fly more than 500-600m without an OSD unless you've got some very clear landmarks to follow. As Alex says, it's a different world up there and it's easy to get lost!
