After much research and much help from this site, I've decided to get a WSM. I've been using a New Braunfels sidebox model for years and years, but I'd like to smoke more with a tad bit less work. Questions: Which size should I get? The tried and true 18" model or the new 22" model? Are there any features of the newer one that makes it better or is it just size? I'll do lots of ribs and shoulders, the occasional whole ham or turkey. Also, are there any accesories I should consider? I want to be ready to smoke something once I get the thing! thanks to all!
