If you'll be hunting in very cold weather like me, pick one with buttons instead of touchscreen.
Having to take off your gloves every time you want to take a look at your next stop or mark a waypoint is frustrating and takes you out of "hunting mode" and into "how the heck can I make this flippin' thing work?" mode.
The touchscreen models have a larger, easier to read display, but like I said before, they can be difficult to use if you're wearing gloves. The Garmin Oregon and Montana are fine touchscreen models, and the GPSmap 64 is a great button-activated model.
Cabelas has the 64st (normally $349, includes topo maps) on sale right now for the same price as a 64s ($299). I just used a 10% off code, free shipping and a few Cabelas Club points to buy mine for roughly $100 less than I could get it at another nearby retail location.
I might be able to match that somewhere online, but I like being able to drive to Cabelas and get instant action if it needs warranty work.
