Anyone here using Streetlib?

I finally got back into my account there. It seems the U.S.A. does indeed do paperback. I don't think they charge for proofs but wanted to chat with someone here who is using this service. Are they dependable? Do they pay on time and how often? Are sales good. I know that depends on a lot but are they good compared to Lulu. Just want to hear someone's experience with Streetlib. I'm going to lose a lot of books but I might can salvage the ones that do sell and move them to Streetlib if the site does well.
