I use the Delorme topo series. As with most of my stuff, it is the older series. In total, I regard it as worth the $$. Again, be careful about uploading maps to a GPS, check that before you buy as I mentioned in the other thread. It does not accept the entire GPS waypoint data from the garmin units. Not sure about other brands. Just lat/lon. identifier. Track and routes are transferable both ways.

That said, I use the maps almost daily. Usually I print out the area and do preliminary GPS/Map coordination. Two copies of the maps (one for me one for Gloria). I keep track of our movements on the paper map (with data from the GPS etc) as we go. Then when I get back, I load the track from the GPS into the program and see how well I was doing with my field work.

I find the detail OK, but no map has everything. I would buy another set, and probably will.
