I've been stuck on the idea of the standard size comic book, printed, since I started running. As much as I love webcomics and digital comics, that to me is the core idea of a comic. (Though I may start moving into some web-based stuff as well.)
Ka-blam are reliable, and have easy to understand pricing. For a small run, they are fantastic. Starting at about the size of this run, it begins to feel like a volume discount would be nice.
