I'm about to implement Recurly http://www.recurly.com/ on my own site, on top of PayPal Website Payments Pro.

Recurly abstracts my gateway's API stuff and stores payment details so I'm not tied to my gateway - much like I wouldn't use a Comcast email address to have the freedom to change TV providers.

Worth a try. Note: I'm a potential customer of theirs and have no other affiliation.

Offtopic: Can I use recurly outside the US? I'd need it for a b2b website and have nothing but a German bank account and credit card. Thanks!
