"Marrying" a POD publisher?
4 better deals (best first)
Publisher	Why are they here
Virtualbookworm	This is the only publisher that actually met all of the criteria outlined in the "What to look for" section of the Is POD for me? guide.
Universal Publishers	Moderately expensive, but they offer a good deal for authors of technical books, they are considered "specialized", and the fact that they offer the possibility of submitting work as a ready to print PDF is a good way to avoid the problems caused by special fonts and the need for numerous graphics and tables.
PageFree	They offer good royalties, a good contract, they give you a lot of control over marketing and they have an almost reasonably priced "basic" setup fee, but they don't screen manuscripts, you have very little control over your book's design, they have way too many things that are considered "extras", plus there are a couple of things that are too misleading for my liking in what they tell authors they can expect.
Llumina Press	There is a problem with their contract, their setup fee is a little expensive and you have very little control over your book's marketing and design, but they screen manuscripts, they have good distribution and graphics are not a problem (or an extra, unless they have to scan them for you).
4 worse deals (worst first)
Publisher	Why are they here
BookPublisher	They will work with the authors to publish works none of the other publishers would ever consider, but they are extremely expensive, they have an exclusive contract that covers most of the author's rights, they offer low royalties and you don't have a way out of their contract. They have recently renamed themselves. This company used to be iPublisher.
FirstPublish	They have the best bookstore discount, and they have a non exclusive contract, but they don't screen manuscripts, they are extremely expensive, and they have a system that forces the author to pay for each book before it is printed in order to accept book returns, so the costs to the author are impossible to predict in the long run.
Xlibris	They have a non-exclusive contract, but they are expensive, they lack flexibility, they offer low royalties and they are immediately recognized as a vanity press. Their books have a retail price that makes them very expensive, not a good idea for those who are not established authors.
YourBookPublisher	They have good distribution, they are a small publisher, and they may be willing to publish your book for free under certain circumstances, but they are expensive, there is a problem with their contract (which is not available at their website), their "Production Plan" is just too bare bones, and they charge a "reading fee" to consider a book for their "Custom Plan" that is almost as high as the entire setup fee with some other publishers.
