I am in the market to get a GPS. I bass fish mainly on lakes varying in size, but will most likely use it everywhere I go. Especially since I night fish during full moon periods, i'll be wanting to be able to find all my little sweet spots with the help of a GPS. I am on a budget, but don't want to get something out of date. But then again, I don't really need anything to fancy. I have looked at the Garmin GPS map 76. This is pretty upscale for me. Garmin also makes all those e-trex's. Does anybody have any recomendations for me, or any tips for buying a GPS?
