I've got a Garmin 2610 GPS - it's great, it has a removable compact flash (comes with 128K) which I can pop into my computer and load up with maps, routes, etc. I particuarly like the touch screen which allows for faster input (I also used this on my motorcycle, which comes in very handy.) It also comes with a remote that allows you or a passenger to enter info w/o having to pickup the unit or lean over to the dash. Its the same operation with the 2620, however, the 2620 comes with a builtin hard drive instead of the compact flash and has all the maps preloaded. For me the 2610 wins out since I also use it on my bike making the unit more suseptable to bumps, which hard drives don't like. Either Garmin makes a great choice!!
