Everyone has their preference, but I like the Motorola Talkabout EM1000R (22 Channels w/sub channels)
That is just one link I came up with but there are more. I picked mine up at Home Depot so if you have one of those near you, check in their electrical department...I didn't see it on-line.

We used this for the CAA this summer and I didn't hear any complaints about not hearing me...even when we stopped.
