Recurring billing with Rails - what are my options?

Question

Before jumping in I\'d like to know what all of my options are, and, if possible their pros and cons.

The two I know of are using ActiveMerchant, or the paypal_recurring

Answer 1

The SaaS Kit is now tested with Rails 3.2.2. :) It doesn't support IPN yet, but it's on to the todo list. With all the info here in one spot, I suppose I have no excuse not to get it done. :)
