I feel like I'm going to say similar things about all of the D20 Cartographer products to date. They are easily worth the $1 with black and white, color, gridded, non-gridded, MapTool compatible (including objects, vision blocking, etc.) versions of the maps. This one is particularly useful as your interchangeable inn, bar, store, anything inside really. Does it really matter if you use the same building a few times? If you rearrange the objects, no one will even notice! With all the features of this product, you can't possibly pass it up if you've got any sense and use pregenerated maps ever.
