I went to one last year, cost me $50 for some of the best seats in the house, dead center, a few rows up from the floor seats.
Then another event was going to happen at a public hockey arena, $100 (+ UFC 137 & $50 went towards a charity that was started up after Shawn Tompkins death for people with the same problem) for a ticket with the only notable name was a former tuf fighter who got knocked out in the first round of fights. This event ended up being cancelled.
