I ended up getting a 62st for a good deal. I think I would have been just as happy with a less expensive GPS, but too late now. Mine is for 95% trails and 5% roads between trails.
Also don't understand how a topo map helps me...LOL
Have only used the GPS once so far and had to use a paper map as well. That should change as soon as I get a Micro card thingy and upload a trail map.
*I downloaded Northwest Trails and that is pretty sweet. Most all trail systems i would use are in there.
