You’re concerned with ongoing costs for fuel and power: The wood pellets used with Traeger grills are more expensive than propane or charcoal. You can expect to spend $1 to $3 per grilling session using wood pellets. Propane is far less expensive to operate in a grill, while charcoal fits somewhere in the middle of the cost range. And beware of cheap pellets from third-party manufacturers that contain softwoods like pine. They burn much faster than hardwoods, so the end cost won’t be that much different because you’ll use more of them. And they can introduce unwanted chemicals and contaminants to your food. You will also have some electrical power costs with these Traeger pellet grills.
***Update: 11/2014: It's been a year now and I still adore this little grill. I've got a kamado and 3 different kettles and this is by far the most convenient and easy to use. The smoke rings this guy puts on a brisket are amazing and the flavor is the perfect balance of wood flavor without overpowering the meat. I've researched about 15 different pellet grills and I still can't find a better value than what this grill offers
