Make a checklist of things such as how often you will use it, exactly what features you need, etc. I just got back from an elk hunting trip in Colorado and my needs were met by the basic Garmin Etrex. All I wanted was something to mark waypoints and to get me back to camp. It did everything I wanted and although I knew nothing about the country, I never once was in fear of getting lost. Without it I might have got lost several times.
