This notice is from almost seven years ago. The Model 1050 would have been either still in production or maybe recently discontinued at the time Outlaw reported this (I don't remember when they sold the last 1050's).

If you see a 1050 on eBay today, the warranty has already expired - all the 1050 warranties are expired now. The eBay ad you mention (in Queens) lists the unit as used, has a picture of it in the person's equipment rack, and is most certainly just a guy selling an old receiver. I would see no reason to suspect him of trying to sell a piece of stolen equipment.
