Was looking up the price of this burner for another thread I was posting in and was surprised to find that it's on a really good sale ($40):http://www.amazon.com/gp/product/B000291GBQ/
I bought it from Amazon for $60 a year ago and it's been great. You should be able to snag free shipping on it too.
how does a sankey kettle do on this? stable?
I use a 15 gallon stock pot on it and it's stable when it's full, not so stable when it's empty.
