I have been using their maps for 3 years and like them a lot. That said you can get just as good of a map for free from GPSFileDepot.com I have used both and their is not much difference in the quality of the Topo map. The only advantage to the Hunting GPS Maps is that the land ownership gets updated every year with new info, where as the land ownership map on GPSFileDepot is from 2011. Used to even be able to get the GMU transparent overlay on GPSFileDepot but I think they changed the link to Hunting GPS Maps website. If that is the case I have a copy of the GMU overlay I could email to you. Just PM me your email address.
