I've looked at all the providers and couldn't find one that was flexible enough and also isnt overcharging, I.e. paying for the service, credit card charges, payment gateway, etc. That said, I've found cheddargetter to work quite nice. Has an API, includes the payment gateway, and provides enough flexibility for custom prices per subscription. So far I've implemented three startups with it. Hope this helps.
