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.
