I'm looking to upgrade my handheld GPS from a basic b&w model with no maps to a model with maps. Looking at the Etrex 20. Any experience with this model, or any other Garmin model with Lake Maps? I don't want to spend the $$ unless it can do what the FF/GPS combos can do (for the most part). I have a basic FF that I'm happy with, but want more from GPS.
