Hmmm, actually when I buy scalped tickets, it's usually because I want to pay *less* than face value (i.e., the Journey/Styx/Reo Speedwagon extravaganza at MCI that I got great seats for at less than face value because we waited until after the show started).
I'm usually on the ball, so I always get tickets to shows I want to see. For now, the only reason to pay a lot for a show is that you didn't get a ticket.
But, sure, there are bands I'd pay lots to see(some I won't admit to here). But I don't want to pay Ticketbastard for the privilege.
