Garmin GPS Map60 CX http://www.abesofmaine.com/item.do?i...60CX&l=BIZRATE
This is the cheapest I could find, free shipping too. This is the one I want, the wife has the 60CSX but it has all the extras with some things not needed.
These are awesome units! They keep sattelites in heavy tree or canyon cover, and you can buy chips with the maps to go in them. Check it out.
We use ours for geocaching, mostly.
