Although I currently do not own one of these babies, I happen to live about 8 miles from where they are made.
And this will tell you how clueless I am, until the other day, I didn't even know about them. I happened to be walking through their showroom on business and noticed them. Let me just say, I am somewhat of a newbie when it comes to the various types and kinds of smokers (I currently have a WSM and a Hasty Bake), but I was absolutely taken back at how well these things were built. They are extremely heavy and extremely well-sealed. Any dummy can look at them and know that they are extremely well made. I personally, would be that dummy.
Yoder is an true Amish community that is highly regarded for their craftmanship in making things with their hands. They have several small town shops where people travel from miles around to buy their well made products. I have no reason to believe that the smokers would be any different.
Again, although I have been around some offsets on many occasions, these stood out to me as a high quality product. As far as how they work operationally I can't comment, but if it was half as good as the product was made it would be a "can't miss".
They did seem proud of their product from a price standpoint, by the way.
