We use Eventbrite for all our Entrepreneurs Unpluggd events, and while they're not multi-day conferences, I still think Eventbrite is the best platform for any size event to use for ticket sales, registration, waiting list, and all that jazz.
Never once had an issue with them on any level.
And no, I don't work for them or get paid by them in any way. They just have a kick ass product. :)
EDIT: The reason I'm even saying this is the author mentions in his post that he switched from PayPal to Eventbrite.
You're right. He said he was switching from PayPal as the payment processor to Eventbrite.
We used PayPal for our first event, but their extra cut on top of Eventbrite's made little sense, so we too switched to using Eventbrite's processor and haven't looked back.
You have to wait until the event is over to get the money, right? It seemed to me that with PayPal, if it didn't get frozen, the author of the article would have gotten his money before the event started and been able to use it to pay for the event's expenses.
