Barrow Tomb is an interesting product. For myself, I've been messing with doing up some kobolds in the style of the old Necromancer's Legacy product from 3.0 and needed something like this. Unfortunately, as noted on the product description page, the map files aren't really made for miniature use. Now note the product does say you can copy them and enlarge them and that the resolution is high enough but that's a little too much work for a lazy bastich like me. However, at the product price point, this is a solid value if, like me, your mapping skills can best be described as... managable. Barrow Tomb includes a player version, GM version, slanted version, as well as up close versions of different sections with room to write down the encounters.
