If I can't get tickets from Ticketmaster or See Tickets, Ebay is my next choice. Do all you can to chase them up to avoid disappointment. Having said that, promoters don't release the tickets until very very late in a bid to stop touting. Doesn't really work though. I got my tickets for MK night 2 last year (Sunday) on the saturday before by special delivery!! I bought them off ebay so the seller didn't get them until 2 days before the gig!!

But yeah, chase it up asap.
