my friend was like that.
so i havent tested out my old 4800+ to see if it works.
But i listed it on craigslist so it would be local, and the customer can just bring their computer over, and test it to see if it works, and if it works then i get my cash, and they get their processor, and if it doesnt work, then i keep the processor and they leave.
just say you havent tested it, and no refund no matter what, buy at your own risk, and all that kind of stuff, and you should be okay. Just think positive till its all over.
