For what it's worth, the gtopo 24k product is pretty fantastic. Recently used the heck out of it on a 10 day hunting trip, it had a pretty ridiculous amount of roads not shown on any other detailed map.
One downside though is they are obviously using some elevation and image analysis to auto detect drainages and mark them as water. A significant number of draws in our area were marked as creeks, when it was actually an ATV trail along the bottom.
Other than that, a very very worthwhile product if you plan on doing any serious hiking/motorcycling/etc and plan on extensive use of GPS.
