POD was by far the cheapest, most reasonable way to go for short runs on the trade pepareback. Same price whether you ored one or three hundred. Traditioanl printing houses wanted 10-11 dollars per at runs of 1,000.
I did find a place called JustBooks.com that can do reall reasonable pricing for runs from 4000 to 10,000 so if I get to that volume and nobody has picked it up, I can have them do it and make good money at reasonable end user prices for both whole sale and my own web sales.
EBook sales (MSReader, Adobe and Activ E-Book) have been fairly good too.
Anyhow, it's been an eye opening and learning experience.
Regards.
By the way, congratulations on your book. I'll order one soon.
