Love my 22" WSM
I bought my 22" WSM last Nov. and I have no regrets. It's uses a good amount of charcoal but... it's a smoker. I do have to mention that if you plan to use the minion method you might run into some trouble. For whatever reason my 22" gets too hot when I use that method. I switched to the snake method described on amazingribs.com and have had good results ever since.
