I could not believe that 1st lot that went, That guy got that 4x4 dual sit down + i think 2 or 3 more games for about 250. unreal! I am very happy with my purchace. I got the Valley Cougar dart board. It was the one on the far wall by APB. works great. 
Those darts were really nice; If only I had a ceiling tall enough to accomodate one. Hah. I have to settle for a Target wallhanger dart.
Vita- Sorry I wasn't clear. Here's how it worked:
The auctioneer turned on 3-5 machines. The highest bid had choice of the one machine he wanted. For example, that Tron machine was in a lot with some real turds, however, the bidder was actually bidding on the Tron alone or "choice". First choice will usually take the best machine, in that case it was the Tron.
Once the ceiling is set, the winning bidder has the option to buy any or all of the other machines at the highest bid. No one in their right mind would pay 800$ for a crummy Jamma conversion of some boring old Taito title, so the auctioneer starts again.
So say if the APB, the Kageki, and the Shootout were in the same lot, and I REALLY wanted the APB. I get in a bid war with someone and I end up buying "choice" for 400$. I select the APB, and I have the option to buy the Kageki or Shootout for an additional 400$ each. I say no, so the auctioneer asks the mob whether they want to buy any of the machines for 400$.
But here is the rub (and why it is done this way besides speed). Lets say I get in a bid war over that APB... at least I THINK the other guy wants the APB. Little do I realize that he wants the Kageki, NOT the APB. This will tend to drive the price up on the APB (or in his case, the Kageki) because it opens the auction to more than the three guys who want just the APB, but to say nine guys who want choice. Say three for the Kageki, three for the APB, and three for the Shootout. The price will artificially inflate. Pretty tricky, huh?
I'm not too sure whether this technique actually benefitted the MOMA. The lots were often lopsided (A Tron with JAMMA junk, etc) and the equipment went WAY cheap compared to other MOMA auctions I have been to in years previous. Cabinets that look as though they had been dropped off of a truck went for 125$ just a few years ago (the source of my old Superstars of Wrestling cab, a horribly converted Pac--now a stunning and beautiful cab that the envy the world over. Haw). My Pac cab would NEVER have went that high if it were in Saturdays auction. Ever.
People were surprisingly thrifty this year, or they were confused as to what the hell was happening. "Am I bidding on ALL THREE machines??" It probably put off the casual home buyer (collectors and route vendors are probably grateful, though).
I hope that makes sense. This is the truth as how I understand it to be. If anyone wants to add /ammend anything, feel free.
