Thank you David Chen for the info about the Dakota 20. We just ordered one!

Found one online for $219. Planning on getting a micro SD card for more space. The AA batteries was a big plus also.

We plan to use it on the bikes, for hiking, and driving backroads.

My SO and I are GIS/GPS professionals, working with expensive GPS units on the job, but at home we are sort of luddites. We have a very old Garmin Etrex Vista that we seldom used.

Now we are looking forward to loading it up with topo maps and files (from the website you suggested) and heading into the backcountry with it.
