Do you just want to print one or do you want to have it availaible for print on demand? If you just want one copy, I would go with Lulu.com. Per book, it's much more expensive but if you go with Lightning Source you have to have your own ISBN and setup costs, I believe, are at least $100 dollars including a proof copy.
I'm sure there are other options but I don't know of any off the top of my head.
