I have the Etrex Legend and love it.. has served me well...
Go for the most Waypoints and Tracklog points you can have... I have 1000 (double that of the Garmin V for example).
Also another big one is the tracklog points, the Etrex have 10,000. Sounds like alot but they go quick when it is putting one every 20 ft on a trail... I have maxed the tracklog points out on occasions...
Do a product comparison on garmin.com it was very helpful to me... realize I use mine for strictly offroad/hiking, so it was a better option than others...
