Tent & GPS suggestions.

[Krabill]

I don't think the 60csx has any limitations. It's a great little unit.

Completely weatherproof.
Mapsource lets you upload, download, etc, etc, tracks, waypoints, etc, etc. . . and share them too.

Two things it does not do
1) No voice turn-by-turn directions. It does the directions, but there is no voice capabilities to talk you through it.
2) Doesn't do paperless geocaching. Don't know if that is important to you or not.

The new 62s does paperless geocaching, which is the only thing I like about it vs the 60csx. I like the old 60csx more for everything else.
