What Ron said.
For grilling, the most used would be my SS Performer. For smoking it would be my mini-WSM. Anything that doesn't fit in the mini goes either into the 18 WSM or 22 WSM. Specifically, briskets in the mini, butts and ribs in the 18 WSM and if I have more or bigger, in the 22.
Other alternatives I have include a 26.75 kettle, 18 kettle, other 22 kettles, a couple gassers and a lodge Sportsman's grill. They're all fun to use!
Not sure what I would add. I already have an extensive collection. I might go with some kind of Kamado since I don't have anything like that. Or maybe a stick burner. Someone listed a New Braunfels smoker recently for $30 and I tried to get that. For $30 it would have been something interesting to try.
