For an extra $4 you get a 8ch receiver and a Flysky module. It's a pain to move the antenna to the module but you could always just sell the receiver and module and get more than the $4 back.
What I'm waiting for is the Frysky x12 due out "soon".
If I wanted to get another 9x I'd wait for the Turnigy 9XR. It has a programmer and backlight built in, an internal Spektrum module, better quality switches, and it takes still takes JR style modules. Supposed to be $50 and out any day. (Though I'm sure they will be perpetually back ordered in typical HK fashion.)
