Also I have seen some bugs with this CCBILL PAID thing in the past, joins appearing in NATS but not in my CCBILL affiliate...

While I like NATS, I don't think that switching to NATS by itself would improve conversions. I think it's often that the NATS programs manage their sites better, update more, have multiple billers, etc.

But I'm sure in some cases NATS would be an improvement. I have seen some custom solutions built around CCBILL on some paysites. Eg. users have to register first instead of paying right away. I have a hunch some of those don't track properly, and NATS would be much better.
