I've been on and off this site for about 7 years now. They are a block time site, which I prefer if I can find one with decent traffic. Payment has never been late and you are paid directly by CCBill, not a 3rd party, which I think is the best way.
The only somewhat negative I can say about the site, is that since things slowed down with the economy, the webmaster isn't as easy to get a hold of. I think he has another job, which is understandable. He is always on Yahoo IM, but at times it does take a couple hours for a response via messenger or email.
