You should also state whether you intend to publish solely online or also sell through brick and mortar. The latter makes Lulu a lot less attractive. Otherwise, Lulu are a great choice for an online PoD store.

Another thing to consider is that if this is your first time publishing, you will look a lot less attractive to a publisher in the future, because they can't promote you as a debut author. I have a bookmark about this somewhere, I'm sure, but it's on another computer.
