It seems that in the geocaching world the Garmin 60CSx is percieved to the best best current unit. How did I get so lucky as to have purchased one??? I really do like mine. So far I haven't seen much in the new models that is worth the extra $$$.
The Delorme units' ability to obtain 24K topo maps seems nice. Not sure I'm sold on their reliability yet.
I still like paper maps best, though I use electronic maps to do lots of pre-planning - usually using Geobuddy software. That is almost as much fun as the trip itself.
