Which billing system do you recommed for a pay site?
 

I'm designing a amateur pay site for a client (this dancer Jennys Nude Modeling) and I was wondering what everyone would recommend as a good payment and subscription processing system?

My client wants a company that customers trust. Especially important is that if the customer wants to cancel a subscription that it should be easy to do, good customer service, and excellent record keeping.

I've been looking at Jettis and CCBill but thought I would get opinions from here.

Thanx, Dave.
