A friend and I are getting ready to head to Colorado for our first elk hunt this year. I don't own a GPS and I'm looking for a little help. I would like one with a color screen so I can load 1:24,000 maps with land ownership overlays. I have found good reviews on the Garmin 60Csx and they have come down a lot in price. I have also been looking at the new Oregon 550t but it is pricey.

Is the screen big enough on the 60Csx to work well with the 1:24,000 maps? Do any of you have any recommendations on where to buy these detailed maps (huntinggpsmaps.com, huntersmaps.com, kmlers.com)? I'm new to the GPS world so any advice is greatly appreciated.
