Best way to scalp tickets for tonight's PAC 12 basketball tournament championship game?

I'm a Vegas local and I wouldn't usually go to these games, but I have a friend in town who really wants to go to the PAC 12 championship game tonight. Craiglist is full of people still wanting $150 a ticket and my budget is more like $50 a ticket. Any ideas? Should we just go down to the MGM grand and ask around?
