I need to get some handheld radios to keep track of the kids while camping this summer. Do any of the Motorola/Cobra/Garmin/etc units work decent? I need something that gets a signal in the wilderness for a couple miles anyway. I know some of them say 2-5 mile range, but I think that is under IDEAL conditions! I have a couple sets of 5 year old Motorola's and have never been impressed. I don't mind spending a little money if i can find something that works well.
