Im about 1.5 hours away from the seller and didnt bother to make the drive after going back and forth with him. He wouldnt elaborate on the pins that needed work but he did say they wont turn on. God knows what that means. 2 big red flags: 1 - the ad has been up for something like 6 weeks now 2- the seller lists the good shape ones high or slightly higher than what they are worth but the project ones way below. That means he probably knows there is a serious issue with them. Could be flooding or boards missing who knows. Not a whole lot of guys own 5+ C list pins and can't at least diagnose them . I didnt sit right with me so I didnt even bother and I normally drive 3-4 hours one way for everything i pick up. Be cautious.
