Quoted from wonderpuddle:
Yeah, I saw the credit dot as well so I'd try to diagnose the issue before making an offer. But I'd think anything under $4K would be a steal from the pics.
I'd suggest never trying to diagnose an issue before you buy a machine. A few things can happen, none of them good:
1) You diagnose the issue. Seller decides the game is worth more now.
2) You start poking around and screw something up further on a game you don't yet own. At the best, seller is really pissed at you now.
3) The seller thinks that you're trying to make up stuff to show him to change the value of the machine. Seller becomes paranoid about your true intentions.
None of that is something you want. Open it up, SEE what the error is, but don't attempt any fixes.
As for price, I think that depending on what that error is, you're looking at a $3500-$3900 example there. Fade, cabinet drilled for lockdown bar, and some sort of issue that needs correcting all contribute.
