To support those of us who use Magellans:
My first and only GPS is (and has been for 3 years) a Magellan Sport Track Map.   I came in with no knowledge  of GPSrs and found it easy to use from the beginning.  Downloadable maps, plenty of memory without needing extra expansion cards ( I think I have about 1200 waypoints in mine right now after a cross country trip), easy navigation buttons, 2 levels of backlight for night caching.  There is only a black/white screen but I find it easy to read and do not feel I need a color screen to differentiate bodies of water on the screen.  Have found it to be very sturdy, through much rough handling and there are features I do not use (terrain projection, best fishing times) but they are included! The built in maps are very adequate for caching if you don't have time to download detail maps.
