I sold my Sport Track to a friend when I bought a Delorme PN 20. The Sport Track was a very good GPS - I think it was more accurate than the PN 20. But I like the PN 20 for its color screen and features that the Magellan lacked. I would still be happy with the Magellan, but I'm happier with the PN20 despite a little more potential error (perceived, not documented, maybe I just need more experience with the PN20 .)
