I wouldn't personally pay a dollar more than $400 and I wouldn't sell it for less than $1,000 or $1,100. At least then I'd be closer to my target gross margin. And I wouldn't drive anywhere to get it. They'd have to bring it to me. My time is valuable. If I spend 30 minutes going and getting it, that's 30 minutes of unbillable time + the wear and tear on my car. I would go and get it if it were $150 or something and the seller wasn't willing to bring it to me, but at that price I'd be worried there was something seriously wrong with it.
You're in the business to make money, not to buy computers. I don't want the gaming laptop - I want the money. It's all about numbers. If the numbers don't work, it doesn't matter how nice the computer is. There's very little I'd do for $100. I mean heck, my diagnostic alone is $75.
