Ecommerce Subscription for Rails

Have seen some conversations revolving around this, but hoping for some current input as to perhaps the best libs and services available for Rails developers at the moment who are implementing a subscription membership based website.

I'm interested in any libs or frameworks with which you may be familiar through GitHub or elsewhere as well as what service has given you the best experience so far for clients and your own sanity? I'm leaning towards paypal and perhaps also incl开发者_如何学编程uding Google Checkout, however there are certainly a lot of other options.

I'd like for it to be clean and to appear as integrated into the website as possible while carrying the trust of a larger service provider such as PayPal and Google.

Additionally, these are mostly micro payments at around $1.00 USD. Sometimes purchases go up to $15 to $30.

• EDIT: Since initial post I've found SaaS Rails Kit (http://railskits.com/recurring_billing/). Has anyone had experience with this vs Recurly? Doing some research as per the first answer, it appears Recurly is the superior option at this point for our model, however this Rails Kit may be an even better option if it has met some very positive experiences in comparison with other options.

The one I prefer: Chargify (soon to be available on heroku)

Another I know but haven't used: Recurly (soon on heroku too)
