I personally have this transmitter and like it. Has built in fail safe, holds up to 13 models. Receivers however are 15 bucks a piece, so you'll spend 45 for the transmitter and the receiver it comes with, then an additional 100 bucks for 7 more receivers if you decide you like it.
It has trim and subtrim, very fast resolution, a backlit screen, lock button to lock the trims and such, throttle hold, mixes, throttle, brake, and steering curves which are adjustable, and endpoint calibration on top of a failsafe. Very nice unit for the price. And if for whatever reason you hate it, you're down a measly 45 bucks. That link is for the U.S warehouse, which is located in Washington State two hours from my house.
