I have used this computer and termlab several times over the past year or two, up until shortly before the trade. It is obviously an older computer, but it DID work. Shavenblazer is a good guy, I've dealt with him both buying and selling. He's always taken the short end if there was one. He's even given me extra wire just to help me out when he could.
I can't understand shipping an item worth over $100 without insurance, but you both took responsibility when you decided to do that. If he had received an amp that wasn't working it would be his job to pay for repairs, the same goes for you. If he hooked up the amp and said it didn't work you would have no way of knowing if he wired it up wrong, or powered it in a geo with stock battery at .3 ohms till it fried.
How can he know if you dropped it during opening it, or sat it on top of a huge magnet or something crazy?
You could have settled this privately but you chose to make a big thread about it. Now even if he traded you back you shot him in the foot, smearing his character and making his computer look bad. Maybe the computer did get damaged during shipping, but that's not his fault, and if it starts right up when he gets it he now will have trouble selling it to other forum members.
I have no harsh feelings, but for people saying shavenblazer needs to man up, I can say this is either user error, or shipping problems, neither of which I feel he is responsible.
Best luck guys, hope you get it worked out.
