to Lulu or not to Lulu? that is my question

The title is pretty self explanatory. I am looking for feedback regarding the lulu.com service. As some of you already know I am working on several projects including a sketchbook, artbook, ebook, sculpt/vinyl, dvd and possible tshirts (hahaha wow).

I found lulu awhile back and am curious if it is a recommended way to make your own books?
Have any of you or friends of yours gone through the process?
Is there any upfront costs? how is the distribution?
the process? headaches?

Any and all feedback is welcome! oh and here's a pic for your click X)




thanks in advance
Joe
