Mine was about £65 delivered from HK, already had TX and RX. I guess with an entry level transmitter, receiver, some spare batteries and a lipo charger, it wouldn't be far off £200. Then you need a camera, video transmitter/receiver and goggles/screen and all the gubbins, so put aside another £200
Then you get quad envy and build something bigger/faster/more stable...

Very well behaved with self levelling on. Need a much bigger field for this beast 
. Gimbal and 8J receiver up and running now but still need to set the channels, and then both the controllers died and I haven't got any chargers for them; need an NiMH and I only have LiPo, and Futaba were out of stock so I have to apply for them to send me some once they come in... SIGH.
) looks a better bet if you want to hang a camera and video transmitter off yours at some point. I had a bit of a headache getting everything fitting well with a good CoG
