Mine is a 2012 model and still going string. The newer models appear to have a different heating element, elongated rather than a W shape; not sure why. IF I were to sell mine, $1200 to $1500. But I know it inside and out. And while I have full confidence in it, it could die on the next smoke. It is 10 years old and has a lot of use. One of those unseen tragedies. Well, that is my 2 cents worth.
