Ouch. I see that guy is making his profit on the shipping!
I bought one of these cameras a couple of years ago for use in my RC
planes (haven't yet), cost me about $60 then. You definitely need to
have the Rx on a TV so you can tune it. Longest range is supposed to be
1000', but I'm sure thats under best conditions.

There's also some concern that the frequency the wireless camera is on
(900mhz) bleeds over into the aircraft frequencies? Never saw any
definite proof about this.
