 $34.99 at allthingsbarbecue.com. Yeah, I like to use those when I'm cooking something like fish or chicken where I need, I'm going to cook hotter in the grill, so I need to get that smoke into the meat, even though I'm cooking hotter on the grill. So I'll light that smoke tube and let it put some smoke in the chamber for something like fish that I might be doing on a plank or something like a chicken breast. So yeah, I love those smoke tubes. They do great.
