If the tickets are being sold for $60, but people are willing to pay $150, then why aren't they offered first for $150? I see the big problem being the middlemen sucking money out without adding value. Let the entertainers get that money.
If I were in charge of tickets for something like a pro sports team, the system I would use would be to put the tickets on sale at some ridiculous price, and announce that the price would drop 1% every four hours, or something like that. Then if you want the perfect seats and don't care that they're $1000, you can get your pick on the first day. Wait a few weeks, and they're $500. Wait until the day of the game, and anything left is $20. There's no need to set different prices on the better seats--they will sell earlier at a higher price.
A system like that would make scalping at a profit nearly impossible.
