I have a couple of fighting cabinets for sale: Marvel vs Capcom, X-Men vs. Streetfighter, X-Men Children of the Atom. These use Jamma pinouts and can play the SF boards quite easily. There are a ton of SF II board for sale on Ebay. The prices of the cabs are $250-$300 so they are good deals for solid working machines with 25 inch monitors.
PM if interested.
