I have a Rino 130 and tested a 120 and the 110. I found the quality of the frs to be poor at best because of lousy speakers, but I love my 130 because of the electronic compas. I would recomend buying a set of frs/gmrs radios with rechargable capabilities because if you use them often, the savings in batteries will outweigh the additional cost of the charger.
I use the frs feature all the time, and as long as you are in open spaces a few miles is not uncomon. I have also used it in the mountains and been really suprised at the distances. Best of luck with your decision.
