just keep in mind, a dual band radio (one that can transmit 140-470MHz) will need programmed to do GMRS. They won't come ready to go out of the box. Likely, you'll have to get a programming cable for said radio and program it from your computer. Some can be programmed on the fly from the mic or radio, but is time consuming. I
I just got a UV-5R last week, and as much as I heard what a pain it is to program w/o CHIRP, I had all 22 channels + the 6 MURS channels programmed in under 5 minutes. Maybe other radios are harder, or maybe I'm some sort of radio savant, but having gone through the process I don't know that I would even weigh it as a factor in my next purchase.
