I'm self-publishing two in-progress JavaScript books with Leanpub, and have had a fantastic experience so far.
They basically share a Dropbox folder with you and let you edit your book in Markdown. For me this means that I'm easily able to work with my normal text editing tools rather than learning something completely new. When I want to publish/preview a new version, I just log into their site and hit the appropriate button, which will autogenerate the PDF, epub and mobi files, putting them in the shared Dropbox folder.
The other nice thing about them is that they will let you start selling your book while it is still in progress, so you can get feedback from real customers about what they would like to see in the book.
