Hi. I have never bought factory 2nds from eBay, but I did buy an entry level factory 2nd acoustic guitar in a local shop several years ago. It came with a 3 or 6 months warranty from the shop, and I'm still very happy with it. For example, this item: Ibanez Prestige ATK1205 NT ASH Body 5 String Bass CAP Sonic Japan With Case | eBay There is no manufacturer warranty. The seller is clear about it. If I believe him, the ONLY problem with it is some discoloration on the neck. I can totally live with that. But I have read people saying there could be, for example, a truss-rod problem, and that wouldn't be seen on the picture, obviously. The shop has a 100% positive feedback, and takes returns 14 days after item is received. What do you think? If I decide to return it (this one or another), the "adventure" would cost me a total 120 USD for shipping in and out.
