"This hits close to home. I'm in the middle of a problem where it appears that a stolen item was sold over ebay. I suspect this is just the tip of a major iceberg."
I hope your problem doesn't turn out to be a major headache. Good luck. I've never bought any large priced items on eBay. Most of the things I've bought are DVD's and books.
I have this nagging feeling that I have stumbled into a major fencing operation. I've been in touch with the jurisdiction where I purchased the item.
