I'm fond of the Garmin GPSMap60CSX. Seeing as how I upgraded from a Garmin Vista I have no real complaints except that the battery life is shorter and, since I have little need for a color display, the 60CSX display seemed a bit washed out compared to the black-on-gray I was accustomed to.

A decent review is here:
