If you're taking subscriptions, I think in general you're much better off getting a merchant account and perhaps using one of the recurring billing services out there. (Chargify, Recurly, CheddarGetter, Spreedly, etc).<p>It's not <i>that</i> much harder to do than PayPal (took me about two weeks), and keeps you from having your customer's credit card info locked into some third party service that you can't get out of.
Here's a good service that has been around quite awhile, and has generally good terms. Dunno about specific recurring support, ut you should be able to set that up with one of the support providers.<p><a href="http://www.2checkout.com/community/" rel="nofollow">http://www.2checkout.com/community/</a><p>Also, google payments may work for you.
