They had TONS (well, tons, IMO) of cabs that sold from $10-75 range.  Turbo's and Pole Positions were selling in the $100-150 range, an Off Road sold for $250, and all the 6-in-1's sold for $575-675.   I picked up a Time Pilot in decent shape for $75.  It SHOULD have been $50, but I got a good deal, nonetheless.  OT, it was working perfectly when there, but after I got it home, the monitor is now "jittery" all over.  Not enough to disrupt gameplay, but it IS annoying!  Most EVERYTHING sold in the $300-600 range, with average pricing around $500.  
A Gauntlet Legends that I thought was in MINT condition went for $750, and a few others (5-6 or so) went for around the $650 range.  A Skins Game sold for $1150, and that's about all for the notable games.  Cocktails sold around $500-600, which someone told me was normal.  I was STUNNED to hear that, and after reading some of Paige's posts, realized I was a complete and total IDIOT not to have bought a cocktail at the last auction I went to.  
At the last auction I went to, they had 5 cocktails (1 pacman and 4 ms pacman's) not ONE of which sold for over $160!  They sold a non-working Ms Pac for $95, which, as soon as it was sold, started up immediately.  Not knowing, at that time, if that was a good deal, I passed on each of them..my caboose is sore from kicking it!
Other good deals....4 pool tables sold for the sum total of....$275.  $135 for the one with a complete set of balls & 4 cues, the rest, $45, 50, & 45 each.  The "puck" bowling games sold for ~$400 each.  I believe "Mr Do-rag" bought his own machine back, but someone would have to describe him to me better than "he wears a do-rag".  
On the plus side, I picked up an empty driving cab for $2, and 4 PC's w/monitors for what I thought was $5, but ended up being charged only $2 for ALL FOUR, each of 'em working.  Nothing special, they're all 166Mhz, but now I've got a jukebox PC, a Vantage PC for the kids, a Vantage PC for my buddy who helped me move my Time Pilot, and a parts machine!  Oh yeah, the driving cab had the pedal left, so tomorrow, I'm gonna pull it off and see what goes on in there.  Mebbe I'll have a new idea on how to make one. 
All in all, I wish I would have had a grand to spend (woulda came home with two pool tables, a puck bowler, a dart board, a soda fountain dispenser w/ice bin, and three more $50-75 games.
