Is this a score? I'm not sure, but here if the SF Bay Area, WSMs are a tough find on CL. I got this 18.5" for $200 and it looks to be in perfect condition. It includes the owner's manual and the cover. I'm picking it up on the way home from work. Not brand new, and not super cheap, but not $325 either. I'm excited, it's certainly better than my modified ECB.
