I would never, in a million years pay over 400 for a ticket to see anything. Heck, I never have paid over 200. So NO I don't think it's a good price. But really, its your money, and none of my business how you choose to spend it. If YOU think it's worth it, then it is. I'm guessing these tickets are offered as re-sale? So you're paying a scalper (most likely) a big profit over what he paid.
If we're not having fun, then why are we doing it?
