We use a Luhr Jensen Big Chief smoker. They are inexpensive, last forever, and do as good a job (in my opinion) as any of the more sophisticated and expensive smokers I’ve owned. The wood chips come from Luhr Jensen and I’m unable to taste a different between types of wood used in the chips. Cherry, apple, mesquite – it all comes out as smoke to my unsophisticated pallet. I do use the insulating jacket if it’s cold out. On warm summer days, it’s not needed.
