Eric,
I have a Garmin Oregon and the HuntingGPSmaps.com WY chip. The chip is very much worth it! I was lucky enough to receive the chip as a gift, but would buy it for even one hunting trip to WY had I not. Not only does it show the private and public boundaries, it lists the owner's names of private sections. The Oregon is a rock solid unit. Search for re-man units. Sometimes Garmin has them on their site. Other vendors list the re-man units as well.

I use a Garmin 62S with the HuntingGPSmaps.com WY chip. Works well!
Eric
