When I'm shopping for a GPS I want two things above and beyond everything else.

1) Excellent Battery Life

2) Excellent Coverage

The Garmin 60CSX has the market cornered in that dept. hands down. They are by far and away the easiest GPS to use and the color screens, along with mapsource topo is excellent.

The Colorado and the Oregon look nifty, but their advertised battery life is much less and I have to wonder how well the touch screen would hold up to real hunting scenarios.

As far as having the FCC licenses, you can simply purchase a 4 pack of the radios and allow others in your group to use them. That solves that problem, but they aren't cheap.
