That is a great price. I had been monitoring prices of all 3 sizes for several weeks, and neither size ever went on sale.
(I ended up getting an 18.5" and assembled it on Sunday, posted about it in a few other threads).
I don't mean to hijack the OP's thread, but had a quick question, and thought I'd ask it here, since the sizes of the various models are mentioned.
I got the 18.5 with the intent to do a turkey. Also with a vertical roaster. (Had this one for almost 4 years).

What's the biggest size turkey I can do using this vertical roaster, on the WSM? I should put it on the middle rack, right?
