Spatial Minds offers many different map packs for different areas of the country, up to 1:24,000 resolution, and satellite maps as well. Easy to import gpx files, automatic save for tracked trails, etc. - lots of cool features, and very reasonably priced (IMHO). The customer service cannot be beat, either (I received an e-mail reply in 5 minutes at 8pm !!!).
I'll post up more as I get a chance to use it on the trail, but I'd suggest you check it out on there very well set up web site if you are looking for an easy to use Topo program.
As I talked with Craig, I found out he's a ham, too; and he is going to try and integrate an APRS interface to Overland Navigator as he gets time...doesn't get more functional than that for OAUSA members...
