Chris Davis writes about his experiences with Lulu, and even shows off some of the books he's published.
have been a LuLu since 2003 or so, and have had 3 'books' printed by them. I can't say enough how high the quality is. If you are an illustrator or cartoonist and have ever thought of publishing, then listen up.
I have had 2 books that consist of just text, and one trade paperback comic printed through LuLu, all three pieces exceeded my expectations.
Chris, also printed up some of his top blog posts into a book, just for kicks... cool idea!
