I bought the Garmin etrex H for doing the hunt tracks, etc. and it has worked great. I use the EasyGPS software, that you can download free, to pull the information off the unit. Once I have my file created I import it into Google Earth. It makes a nice map over the satellite image.
If you go to http://www.rappahannockhunt.com and look at the blog you can see what we've done with it. I am amazed at how many people really like reading the reports with the imagery and stats. People that hunt then go home to look up the images to see where they have been.
