The bigger question here is what is it worth to YOU?
If it's something you are going to part out, or not play, then I'd pass on it.
Let someone who will really appreciate it have it.
If you're just taking it to resell it, I'd pass as well.
Let the other guy worry about selling it for what HE can get for it, and then pay you what he owes you.
If you really like the game, and will play it, then go for it.

My take on games is the same as my take on any other "collectible".
I was out hunting with one of my friends, and his DAD'S gun (that he borrowed to go hunting) bounced across the seat of his truck, and hit my bow.
He about freaked because it was a "collectors edition" Weatherby rifle, and his dad was going to kill him for getting a scratch on it.
My thought is why buy something if you aren't going to USE it, and ENJOY it?
By contrast I have another hunting partner that took a "vintage" Winchester Model 70 (low serial number) to THREE gunsmiths, to have a scope put on it, before he found one that would actually DO it.
They kept telling him about how it would "lower the value" of the gun, and he should "sell THAT one, and buy a different gun to put a scope on", etc...
He LIKED that gun, he ENJOYS shooting that gun, and he WANTED a scope on it.
His take was that until he SELLS that gun, which he isn't going to do (he feels that's his kid's problem), HE isn't losing anything on it.
My point here is that stuff is only worth what YOU think it's worth.
Beany Babies are a good example.
Look at how many people "invested" in them a few years ago, and what they are "worth" today.
Getting back to arcade cabinets, there are certain cabinets that I would personally pay MORE than what they "go" for, if they were in good condition.
Then there are the others that I wouldn't pay LESS than what they go for, even if they were in PERFECT condition.
