I have an X-arcade two player panel that has been on the shelf for long enough. It got about six months of play several years back before I built my custom panel. Minor cosmetic flaws at two of the corners, and two small screw holes on the underside. Other than that, it is in perfect working order (I tested last weekend). I have the original packaging, cables, and the beta version of their USB cable.
$55 + Fedex shipping, payment via paypal. PM me if interested or for further information.
Thanks for looking.
Edit: Sold!
