I have the 62st and absolutely love it. Has everything except a fur seeking option to show you where the animals are. Be sure to get the Birds Eye Imagery on it through the garmin website. Its a satilite image overlay so you can see the open areas around you when you hunt which gets you real familiar with new areas quick.
I'd try ebay or amazon to get the best price. I just saved $100 bucks on the Rino 650 on ebay. Not that I needed another great gps, but my buddies and I decided it would help us if we knew exactly where everyone was during our hunts. I'm tired of people not being where they are supposed to.
