Thanks everyone for the advice. I've decided to pull the trigger on the basic garmin 78 for $200 at westmarine. I would have liked the compass and barometric altitude features of the 78s, but not at that price difference. I also got the garmin 24k topos, since I'll be using it for xc skiing and hiking as well. We'll see if it has enough of the backcountry unmaintained roads.
