GFED-
The particular site i have in mind is not CCBill, however i think you should take a look.
It's a stellar site and the conversions are great (its new and not saturated).
Check the trailers... you won't be disappointed.

If you do decide to test a site that is not processed by CCBill this is the one would be worth your while.
