I thought the story might end with "...And then I did the ethical thing and told them that the game would be worth $2800 if it were error free. Getting a tech to fix the problems would cost betw. $200-$300. But since I have the know-how, I could do it for $100 in parts max. But if you insist on just wanting it out of your house, I wouldn't be able to sleep if I didn't at least give you $1500." Or, I could fix it for you for a couple hundred bucks and you could sell it for what it's worth to someone who really wants a Shadow."

But no.

By the strictest definition of it being "their problem", you're right. But in the name of being a good and decent person, especially with someone who lives a mile from you (they're practically your neighbor), you could and should take a different approach.

But I understand. It's dog-eat-dog and screw everyone else. Hey, the guy got a great deal and that's all that matters.
