Hey III, good onya for what you've done with your stuff.
As for Lulu, I think they're great. We used them for the Stories of Strength anthology for disaster relief we put out after Katrina hit. We had the book available for purchase two months after Jenna conceived the project, and that was our timeline. Lulu had it available for sale almost immediately after we had the book ready to go.
To date we've sold 1159 copies, which puts it at #55 on their top 100 sellers list. Mind you, we had dozens of people all over the world actively pimping this book, and more than half the total sales were made in the first month or so. We also had a few very well known authors contribute stories, including Orson Scott Card (Ender's Game), romance novelist Robin Lee Hatcher, and Wil Wheaton of Star Trek fame.
With all that going for it, we still haven't sold very many copies when compared to what your average book from a traditional publisher will sell. But Lulu was the one place we could go to get a book out in a timely fashion. If, and only if, a traditional publisher had wanted to take on the book, we would have been looking at a much longer lead time, possibly over a year.
So, if print on demand is the right thing for your project, you'd be hard pressed to find anyone better than Lulu.
