If you don't mind going to $399 take a look at the new
Airtronics SD-10G here . It's on sale now for $399 with one 10 channel receiver. IMHO this is one of the best radios on hte market right now. It'll store 20 models which can be expanded with memory cards to hold as many planes as you want by simply swapping cards. All switches are triple throws and there is triple rates on everything. Also, I think that Airtronics currently has the best prices on their line of receivers for 2.4. 5 channel - $49, 6 channel full range - $59, 6 channel park flyer - $49, 7 Channel - $76, 8 - channel $99, 10- channel $129.
While I have both JR and Futaba 2.4 radios the Airtronics is my radio of choice and the radio I have all of my planes on.
