We just bought the Garmin RINOs. If you want to spend the extra money, they are terrific units. The all-in-one GPS/Radio units are easy to use and the radios work as well as any of the FRS/GMRS units out there. Thing I like the best is you always know where your hunting pardners are.
Highpower, my hunting partners and I all use RINOs, but we have to carry an extra radio on a different channel to talk to each other. We have found the range to be VERY limited for the radios. I agree, it is great to bea able to tell where the other guy is, but we have found it only works out to about 1/2 mile. Maybe the radios have gotten better in them, I got mine when they first came out.
