i need a new reciever for my other gasp! plane projects

i had to rob the planks to fly my heli but now i want to do both so...

i was looking for a cheap 7-8 channel futaba compatible reciever and found two in the $50 dollar range, the hobbico command 7 ch dual conversion and the tower hobbys sys3000 7 ch

i mean really, dont they all do the same thing?
