Depending on your time frame, Traxxas will be releasing their 2.4GHz radio with the E-Revo BLE. I'm sure the eBay chop shops will have them on there. But I bet they'll be pretty basic though (no EPA or other bells and whistles).
Trx AM radios aren't the best, but they are my favorite feeling radio. The handle fits perfectly IMO.
Other than that, do you want to use the same radio on multiple r/c's? If so, multiple model memory might be something to consider. The Spektrum DX3s is pretty feature rich and has a 10 model memory IIRC.
I have the Airtronics MX-3 FHSS... It feels great in the hand (big difference between the traxxas stock radio)... Lots of rang, very responsive and it has a nice set of features that will keep me happy for a while...
I have not found any issues with it yet. I think it makes a nice option.
