I have a Garmin GPS. It costs between 100-120 dollars. It is a good GPS for the price. Stores 500 waypoints, has the track-back feature and you can save routes with it. It does not have a map feature though, but a GPS with built-in maps cost 2 or 3 times what I paid. I don't really need the map features anyway. As long as I can tell how far away I am from other points and can save these points and routes for future reference, that's all I need!
