Been Geocaching a couple of times and want to get my own unit. I can spend around $300 and want to get the right unit the first time. Lets compare the Legend C, the Vista C, and the 60C. Is the 60C antennae really that much better than those of the etrex? Is it worth getting a unit with an electronic compass and barimetric altimeter? How much do we care about loading US Topo or do most just follow the other screens and stick with the basemap? Most importantly, which unit will get us there most accurately while leaving some cashola in the ole pocketbook? I'm probably leaning most toward a Legend C with the US Topo loadable maps. What to do?
