Any of the Motorolas. I use a Moto GP300 to scan the FRS stuff in the shack. If you want to work a GMRS repeater, you'll need a commercial radio.
But if you are looking for simplex only, reconsider going to a place like Gander Mountain and getting one of the high end Motorola 22-channel GMRS/FRS radios. That way you don't have to hook your radio up to a computer to change the freqs or the PL.
