I was all set to buy the Futaba 6EX a year ago, then the brought out the 7C 2.4G at the price that the 6 had been at. (around 310.00 w/servos). As was mentioned, the extra channel was only part of the reason to step up. More mixes, more programing options, and a timer that the 6 ch didn't have. My best suggestion is to buy the most you can afford (or justify). It cheaper now than buying a second one later.
