Are you looking for a complete cab (functional)? A JAMMA cab?, an empty cab?
There are various stages and conditions.
I'm not far from SJ and have a nearly restored Point Blank2 cab I am considering selling.
There is however a Super Auction on Dec 3 or 4 at Santa Clara fairgrounds, which might be your best bet.
There are also quite a few on craigslist in the area.
