I did a portion of the Great Divide route this summer. I bought ACA maps, but I also used my Garmin Vist HcX gps. I bought Garmin's topo map dvd. I used the ACA map to program waypoints into my gps. You could do the same with forest service maps, etc. The only issue is when there's a trail on a map that doesn't show up on the Garmin topo map. It doesn't like to route you cross country. (Or at least, that was my problem - it's also very likely you could make it work, but I just didn't know how.) Once I had the routes programmed the gps was very helpful.
