I'm looking for a used Garmin yellow Etrex for my 11 year old nephew. It doesn't have to be in the best shape as, at his age, I'm sure it will be in rough shape by the time he's done with it. He loves caching with me, but he also love carrying the GPSr. I'd rather he play with (and potentially damage) his own, but can't see paying that much for a new one. Any help would be appriciated. Thanks!!
