I don't know what it said before but listing now doesn't say to pay outside of eBay; it shows payment to be made through paypal and that there is a 14 day return policy. Imo eBay and PayPal should cover it provided buyer pays within eBay and follows eBay rules. Interested buyer can always contact him solely through eBay messager as well; ask him for the machine's serial # then research it.
I'd steer clear if he didn't respond to people's queries. I'd probably steer clear anyway ~ it's a lot of $ for a 0 feedback seller.
