I have an Garmin etrex summit. It's one of the cheapest units butI like it a lot. The unit has an electronic compass in it. When your using it to direct you to a particular spot, the compasskeeps the arrow pointing in the right direction even when it might not be getting a good GPS signal. Then when it gets a signal again it will make whatever smallcorrection may be necessary. That's a huge advantage. My old Magellan unit would sometimes point one way and then after I had walked a block or two, the arrow would start flipping back and forth and all the sudden its telling me my stand is the opposite direction. I hated that thing. So, whatever brand you get, I encourage you to consider one that has an electronic compass.
