I dealt with him once on ebay. This was before paypal so I sent him the payment how we agreed upon and when he received it he said it won't do and wanted it another way. I pointed out that we already made arrangements and before I could even respond I've got negative feedback and he reported me to ebay as a non paying buyer. So I turned around and reported him as a non selling seller. During the non paying arbitration process he lied repeatedly and even denied ever getting payment at all and ebay did something to my account and threatened to close it completely. I ended up forwarding every bit of communication with him to ebay and in less then a day they put everything back to normal and removed his negative feedback and dumped the whole mess on him. This was all over a $10 or $15, no way would I have trusted him with a bigger deal or anything at all for that matter after that.
