Currently have a Garmin Nuvi (Vehicle), a Magellan eXplorist 200 (Caching) and a Garmin eTrex Legend C w/MapSource City Select v7(Caching).
HAD:
Garmin eTrex Yellow
Garmin eTrex Legend
Garmin GPS V (Used as my primary vehicle nav for over a year!)
Garmin Quest I (Used for about a week and traded up to the c330)
Magellan RoadMate 760 (Didnt care for map interface, sold it)
Garmin StreetPilot c330 (Great unit, however it was sold to upgrade to current Nuvi 350)
All are great GPS units and worked as advertised. Still getting used to the explorist. Havent used it enough to give a full opinion as of yet, but me and hitman are going to be doing a few more caches next week, so it should see PLENTY of use!
