The GPS I prefer for use in the field and probably the best bang for the buck is the e-trex VISTA HCx for $207.90 w/free shipping from

If you get a Garmin NUVI, several models can also be programmed to operate for both on road and off road use. The City Streets Navigator program is always displayed as the top map layer. It can be selected either on/off so topo mapping software can be displayed under it for back country navigation. The free topo mapping software from
www.gpsfiledepot.com will work in the touch screen NUVI's.
Many people do not know they can install multiple mapping programs at the same time in their GPS units and toggle which map layers to use. Garmin does not put that info in their user manuals. I guess they want you to buy multiple GPS units. Here is a web link that describes how to select which map layers to display (the stuff that is not in your Garmin user manuals)

I hope this info helps. Good hunting!
Thanks for that link FurSniper!
I've got a Garmin Oregon 400t......first GPS I've ever used, and I feel spoiled. Love the Topo Maps, and seeing where the various land boundaries are. Awesome unit!
