I had weeks of no luck here on Interference. I went to u2midwest.com and the first day registered I got the exact tickets I wanted (in the secion I was hoping for, for face value).
Unlike eBay, Craiglist sellers don't have to adhere to any accountability. I bought two tickets for an Oakland show during Elevation and the tickets ended up being "stolen". When I got to my seats the buyer of my tickets had duplicates from TicketMaster stating that any other tickets for those seats were invalid. An usher at the Oakland arena told me that some shady ticket agents at Ticketmaster "pocket" tickets. The original buyer really doesn't get screwed because they just call saying they never got there tickets and are then issued duplicates. Luckily that same usher found me a good place to stand at the arena but for a minute I thought I was going to be escorted out of the arena.
Don't get me wrong, Craigslist is a great place to buy other things but be very wary of tickets.
