Found a 2 star in a Facebook market group that is in really good shape. The asking on it is VERY reasonable, and the guy says nothing is wrong with the smoker, he just doesn't use it. It has been kept in a barn, and appears to be in perfect shape, if not a bit dusty. He claims it is 5-6 years old, but it has the newer style controller on it. My question is how much updating would need to be done on it to bring it close to the 2017 smokers?
