This smoker Is for sale locally. I haven't looked at it in person, but they sent these photos. I don't know anything about this model smoker, so any info by someone knowledgeable would be much appreciated. I do know that they aren't being made any longer. How can I tell if this is the older version built by New Braunfels and not the cheaper version by Charbroiled? Is it a smoker that one can maintain temp fairly well? Do you see anything missing? What would be a fair price for this smoker? What would it have sold for new? Thanks!
