I have the classic 2 and have bought cast iron , the ash basket , bought the smoke ware vent because the dome that came with it is not near as nice and binds up way too easy. But with all the add on’s still love using it weekly . Now I get the joetisserie . With high hopes I installed and what a failure in the fit , absolutely pathetic that it doesn’t fit. 
I went back to see if I ordered the wrong one but nope. Just how it fits. As pricey as all the accessories are one would expect them to fit and be able to use with the divide and concur set up. 
Now I’m in for over 2k with accessories and really wish I had looked into other smokers that are more versatile as I do like multiple types of cooking. 
I was going to order the doughjoe next but I won’t be ordering any other accessories now.
