Membership / subscription plugins – alternatives [closed]

Does anyone have recommendations (backed by experience) for a membership plugin that can

• Provide for recurring subscriptions via PayPal
• Allow selected posts to be visible only to subscription members
• Allow selected posts to have come content that can be viewed by anyone, and some content that is only visible to subscription members
• Good support that recognises that the urgent support needs of payment processing not working.

I’m reasonably capable of running a Google search for alternatives – what I’m after is any actual experience (apologies if that comes across as slightly rude!)

Key requirements are reliability of the integration, informative error messaging, and support that recognises that payment processing is important and often critical.

To be frank, my customers and I have only had miserable experiences with all of the various alternatives. Had I found a suitable one myself, I wouldn’t be developing one in the background. 😛 (And no, the one I’m working on by no means ready yet.)
