i have used the garmin gps products for years, gps 38, 40, 12, etrex and etrex summit and have had no problems with any of them. just purchased the rino and it seems to be a great product in that it combines the radio and gps together. the rino comes with a lot of bells and whistles that you may never use, e.g. calculator, stop watch, alarm clock, calander. takes awhile to work your way through the user manuel to set it all up, but once you accomplish this you are good to go. it does come with 8 gmrs channels and you do need a licence to transmit over them and it will Not transmit your postion to another user while using these channels. i would recommend the rino unit only because it combines the radio and gps together. my other recommendation would be the etrex summit. only complaint i have had so far is that the postions are shown in small print and they are hard to read. have sent an email to garmin on this to see if they can enlarge them. in case you did not know, you can go to the garmin web site and download updates to your units. anyways, i found if you combine the gps with a good map program like maptech you can't beat it. just my input, have a great day
