Excellent condition (one minor chip on the lower right front though-- black laminate chipped)-- as per the description from XArcade below. Sells for $199. It's yours for $100 plus shipping which is going to be a lot since it's super heavy!...
NEW PRICE AS OF 2/24--- $75.00!!!!!--- or I will be happy to trade. Let me know what you've got.
Or if you're local to Syosset, NY you can pick it up for free!--- I'll take a few photos soon. But it looks obviously like this one....only BIGGER. This is their out of stock XL version. Basically it has the dimensions of a full 2 player panel from an arcade machine.
