I recently purchased huntinggpsmaps for my 60CSx, and so far am happy with it..

I just purchased the WA/ID/OR combo maps from these guys and installed in on my twp Rino 530HCx radios and love it so far. I was able to "scout" on the computer, make some waypoints, move them to my handheld and check out new areas that I have missed in passed scouting attempts. Shows private property (thought not the names on this map), DNR, State, USFS, etc using different colors on the map so you have a pretty good idea of where, especially on land that switches between private and public lands. You can get the same programs for individual states that shows the landowner names (based on tax records) but they did not have that information for 2 counties that I like to hunt in so I passed and got the three state for the same cost ($99 for a chip, $129 to download, or $139 for CD). I had a problem or two downloading the maps and they were great to help me out and send an extra cd when I had problems.
Doesn't have all the "travel" features that my phone has such as showing best prices for gas, where to eat, where to watch movies, but it has great topo features, every road in the mtns shows up, includes all GMU and hunting units for Washington, Idaho and Oregon, does include streets and addressed for every city, and is very detailed for what I was looking for in a map.
