Its really hard to resist ebay when you want to see a gig, but there are alternatives, and theres plenty of time to get sorted. There's bound to be more tickets released over the next few hours/days/weeks
edit: and ebay prices always come right down after the initial panic dies away too, so if Musebay doesn't come through for you in the end you will always be able to find a ticket for a decent price nearer the time as a last resort
Don't know if any of you have already read this, but Trent Reznor explains the ticket scalping situation pretty well here:
