looks like for about 300$ i can get 316 stainless elbow, six 24" sections, and rain cap from "the coal shop" in springwater NY. found them actually on ebay and then looked up after noticing they are in NY. Amazon has the cheaper grade stainless thats not good for corrosive/acidic.
I would love to find 2 stainless 55 gal drums and do entire stove out of it!!
