I just bought 2 recently. A 22" and an 18". I'd ercommend that if you can (I know it's hard) try to save up $50 more so you can get the 22". I really like the 18" (thanks Jaybird) for ribs and chicken. The 22" really kicks a$$ for butts and briskets. Tons of room. Just thought I'd let youknow how it went with my recent purchases of WSMs. Either way, you'll love the one you get.
