If you pull the trigger on that thing, you better price out one of those controllers. Probably a reason they are selling it at that price before fixing it themselves.
Yup. Be prepared to to spend twice as much on the Yoke controller than you did on the cabinet - unless you get really, really lucky on eBay. Basically, you're competing with people who are restoring a Star Wars cabinet and MAME cabinet builders. Both groups are prepared to put down serious coin to acquire it.
There's a company that made reproductions for $350 - but there's a little controversy about order fulfillment, business practices, etc. at another message board I frequent.
My opinion: not exactly a machine collectors are clamoring for and will take a bit of money to get playable. Only worth it if you have a Yoke sitting around and really, really like that game.
