Great score! Is this your first wsm?
No Gummi, it's not. I've been perving over the WSM's for 4-5 years. Apparently my wife had heard enough and got me a 22 for my birthday this past March. I know...I know...amazing woman! Within a week I picked up a Maverick ET-732 and a Pitmaster IQ110 and I couldn't be happier with the whole setup.
I have a goal of entering some local BBQ comps Spring 2015 so I was looking to pick up a used 18 WSM to go with the 22 off CL sometime this winter. Figuring then they would be priced the cheapest. With this one for $40 bucks, I had to move up my timeline. Couldn't pass up that kind of deal as I didn't figure I would find one any cheaper.
Hopefully the wife remains amazing later next week when it shows up in the garage!
