What provider to sell tickets via Facebook?

[gavin]

I run a pilot event 16 March 2013 with Ben Glanville.

On the Facebook page (http://www.facebook.com/events/135448559964298/) I set up for the event I see:

Add a link for guests to buy tickets

Has anyone sold tickets to an event on Facebook? If so, what provider did you use, for Facebook don't offer ticket buying, just a link to a 3rd party ticket buying service.

I tried adding a ticket-buying link via Paypal, but not successfully. Can you sell Facebook tickets via Paypal?
