Daeven, wish I could have been there. Do you live in the area?
What was the MAME machine that was sold? Diamond Plate on it? Buncha guys with black shirts and cowboy hats around?
I'm in the western Chicago suburbs, as are a few others around here.
The $1700 Mame cabinet was nice, but nothing special. It was built in a generic arcade cab with original, but nice & glossy side art. The control panel had a joystick and spinner, and ink-jet-printed, plain paper CP artwork covered with plexi. It had a flat-tube PC monitor in it that wasn't even decased. I think it was a 17" monitor mounted vertically.
I got there early and powered it up. It went in to Windows and didn't even pull up a front end automatically. Later, an adult, probably in his late 30's or early 40's and a 10-year-old were there to work on it. They stuck around helping people use it most of the day.
