He should not be offering / spamming outside of ebay like that. Strike 1.

He only accepts money orders, no escrow or any way to protect yourself. Strike 2.

He says he will give you a UPS tracking number before shipping. If he is sending this from Italy, would he send it via UPS? If so, how do you know there is anything actually in the box? Strike 3.

I would thank him for his offer and report him to ebay.

If you really want to try it, make sure he sends you a photo of the player, powered on and showing the serial number on the VFD, set with a newspaper with today's date in the background to prove it is a recent photograph. I do not recommend it, though. Find a different seller.
