This wsm18 was a gift but I couldn't get it running right with charcoal. Some experienced smoker builders helped me do this. The burner is 15000btu. The burner, box, and regulator cost less than $40. I used water last year and cooked at 225 initially, and then closer to 250. This year I'm using a terracotta pot and plate, no water, and just did a hot and fast picnic shoulder at 275. This thing runs pretty stable and without further adjustment, at 225, 250, and then 275 for that shoulder. It was running at 300 for a while before I dialed it down to 275.
