If you want a cab in NJ, I have a Jamma cab - it was a Final Blow cab until I converted it for my mame project. It's complete with 19" monitor, marquee, monitor bezel, and a coin door that is already wired to go into a PC's power supply.
The only thing it will need is a control panel built for it, unless you want to reuse mine by just adding buttons, sticks, and a trackball.
It's yours free if you want. I'm in Brick (Ocean County, exit 88 on the Parkway.)
