I had a great time meeting up with HagHore and Nannuu.  My game plan had slots only on the shopping list, so I was out of there before the good deals on cabs.  I knew Nannu would buy something and I'd hear "after I got it home, I found out it was a galaga, with perfect sideart and the boardsets were inside wrapped in anti-static bags with the marquee and bezel in bubble wrap....not bad for a dollar"   

That $2K mame was definitely a homebrew.  There were holes left in the CP from a previous overlay, and the coindoor and cab in general were in disarray.  I beleive the frontend was Mamewah.  It had real simple directions and convienient "enter" and "exit" buttons on the front just near the coindoor.  Noobs, I mean people were lined up to come see the amazing multiple arcade machine emulator (hey what a catchy name).  
2 down to the left were some other questionable machines.  A midway cab turned into a  "class of '81" went for 800.  It had a 25" screen and, for me, made the games unplayable.  I found myself looking up and down and up and down just to get bearings of ghosts and Ms Pac.  The other one was a Tatio cab turned 6 in one.  Fairly clean, I can't remember the exact price it went for, but it was over 700.
