Self Publish v On-line Publisher

This week Matt showed the class (in true Blue Peter style) how to put a book together. He made two. One with staples the other with rivets. They both looked great. He's obviously made quite a few books and he made it look really simple. It's a tempting option. 
I'm still planning to get a book printed by one of the on-line publishers but I may try making my own as well.
I've now played around with the software from Bob Books. It seems to be able to do everything that I need but I've found it slightly less user friendly than Blurb.

I'm downloading the software from ubyu while I'm writing this. I've seen a sample done by them and it was pretty good.
