Only slightly derailing the thread (I hope), I love your work, and the counters have been totally awesome in game play.
Have you considered doing a collection of "effects" counters for play (Flaming Spheres, Wall of Fire squares, Blade Barrier squares, etc). With the PDF files, where you can create as many copies of something as you need, it would be easy, and cool, for all of the Divine and Arcane characters to be able to actually lay down actual graphic representations of their spells and prayers, perhaps even printing them on transparency sheets to allow viewing the underlying maps.
Just a suggestion of something else I'd spend my money on.
