I have the Jamma one (which is better than the one one real hardware actually), in a Defender cabinet and it is awesome. I spent about $400 total on it (bought the JAMMA WM board, repro bezel, new panel, and original marquee used for $300, spent $50 ish on the Jamma harness and power supply, and the cab was free and I am valuing the monitor at $50, since I can't remember where it came from).
