DX4S with MR200 RX (2-ch) or MR3000 (3-Ch) operation... "Water-Resistant" RX's... Range is excellent... Lot's of programming features. Reasonably priced.
DX3S-Pro if you must have the top of whatever line, but honestly, the DX4S is a great radio and less $$$.
Those would be my 2-choices if you are looking for a nice pistol radio.
