Hard to tell from the pics I received of it, but I'd hazard a 6 or 7 out of 10; I used to see these guys fairly frequently 10-15 years ago in the auctions, but these days very far between; hell, any upright is hard to come by now, unless its a bloody Golden Tee. Anyway, I've always wanted a KI machine.. I never liked fighting games, but that one I really really loved; played the hell out of it back in college, and its my favorite overall cabinet design (the classic Midway cabinet. same as MK and NBA Jam and so on.)
The real problem here is buddy boy way overpaid for it, and now that he's selling it, wants to make up his pain; since I happen to want it fairly bad.. probabyl my last cabinte pickup ever, I'll have to pay double what its worth... but screw it, sometimes you lose
Over the years, mostly before I got married, I went through probably 1000 or 1500 pcb's, and a half dozen cabs; but I sold most of those off over the years, and each move I shed some machines. Right now I've got only an Omega Race cocktail and a ... general, nearly home mae cocktail that is super awesome (I call it the Tardis, since it has sticks on all 4 sides so can play vert/horiz games equally well.) My last mach8ine, a generic converted into a sF2, I let go last move.. sigh

Anyway, I can't take up all the house space anymore, kids and all, so I've been shedding a lot the last few years. I'm giving my Omega Race to a buddy there, to make room .. so I'll have my super cocktail, and the KI. Both great cabinets.
Long term goal, when kids grow up more, is a full size bar clearance billiards table, wet bar, arcade machines, pinball machine .. the Man Cave

But these items are all very big, so I'll settle for two arcade cabs (plus my enormous stash of parts and pcbs .. I can probably still build about 100 games from the parts, plus a stack of Neo Geo MVS carts and A/B boards for CPS2..)

Somehow, when you're younger, you don't have the room.. but you make the room, and squeeze these puppies in; then you get older, and sheeit, so you shed them. But then, if your'e me, you say fuck it, and get some back
And a Picade...
