First and foremost, as to all your questions about are kks that good..yes they are, and then some. There’s not much of a used market, buyers simply don’t get rid of them. Secondly, the warranty doesn’t transfer, but it’s actually fairly rare that that’s an issue. The other issue is that when used ones do appear, the value holds up really well, so it’s unlikely you’ll find a “deal” on a used one. Kks don’t lose tiles, if you’ve seen pics of large patches missing, it’s either a damaged grill, a grill that got moisture under the grout and freezing occurred, typically from not being covered, and most commonly, it’s not even a kk, but likely a Richard Johnson Kamado, which is a story in itself. I highly recommend biting the bullet and ordering a new one from Dennis, because all new grills come with him, almost literally. He’ll help you with a used one, but it’s not the same.
