I remembr a guy from several years ago - Steve Lancaster I think the name was. He developed what he called the Little Drum Smoker and claimed it worked wonders and burned forever. It was only like $40 and received many great reviews. I think he destined to go with larger versions, but never got around to it during my tenure on that list. Those shown are nice - little pricy for what they are and compared to what was available for $40..
