Servo City is, or has been, selling Futaba r148df 8-channel receivers for $49...that's more than 1/2 off. If you buy a Futaba receiver make sure you buy the correct frequency range (high band or low band) to match your transmitter. If I'm not mistaken, Low Band is channels 11-35 and High Band is channels 36-60.

In regards to the Super 8, it is a great transmitter. I fly with one and love it...8-channels, 8 model memory, lots of programming capabilities, an all around great performer. Just so you have something to compare to, I bought mine new in the box from a member here on RCU with 4 s148 servos, switch, 600mAh battery, r148df receiver and the manual for $270. It had never been used. Good luck!
