How do find the topo maps, Laurie? What "scale" are they? I.e what map series 
are they based on?

And do you think the touch screen is useful? I was thinking it would make 
naming and searching for tracks and waypoints easier because typing would be 
faster than the move and select method on the non touch models.

About turning it off to save the batteries, does that mean you have to start a 
new track, say, after lunch?

I believe all the Garmins come with what they call "base maps", which I assume 
are much less detailed than the topo maps. Can anyone tell me if these are
