eBay is definatly the place to get 95% of all your R/C equipment!
I got my Futaba 9 CAP for $350 US (BRAND NEW) when it is sold for $650 at the local hobby shop
saved on the taxes as well (opps, I don't think I should have said that)
I buy my airplanes there and if available my engines, receivers, servos, everything comes out much cheaper
just make sure you read all the information the seller is providing, as a full time seller myself, I know this is a problem
people bid, win the auction and then say "but I didn't read the whole page and didn't know..."

Good Luck
