This is the smoker I got my dad for fathers day.
It's a neat little unit. It's fully electric and instead of using wood chips you use little pucks that you can pick up at any canadian tire. There's a heating element at the bottom that heats the smoker and then a little hot plate that burns the puck to create the smoke. After the puck is burnt out the dispenser automatically feeds another one onto the hot plate. They normally go for around $400 but i picked one up last year for $250. Best investment ever.
