Just had to go through a buyer dispute with PayPal due to some 19yo kid in California saying I sent him a damaged Neo Geo multi-cartridge. PayPal decided to side with him instead of me, even though it was clearly sold as-is, but was working fine when it left my hands. I'd suggest not selling anything to arcadenova on Ebay, aka Sebastian Saldana, aka Ramon Garcia. Yeah, two names associated with his PayPal and Ebay account.
As for PayPal, I've sent them a rather lengthy letter detailing the faults in their lack-of-findings and demanded they re-investigate the case. I have a feeling I'll be permanently closing my PayPal account soon here if they're going to side with kids over common sense reasoning.
