There may be some here that are as slow as I have been, so I thought this might be an informative thread for some of us. I have been chomping at the bit to order a Yoder YS640 and have researched it until I am blue in the face. I have found nothing but rave reviews about this pellet smoker. I decided to place the order and then sometime during the night it came to me, "I wonder what fuel cost will be?" It seems that most everyone that has the 640 must be smoking a great deal more meat at a time than I would be. I usually smoke for 3 to 6 people which means that I am only doing one brisket or one butt at a time or maybe two or three racks of ribs at once. The YS640 seems to be consuming anywhere from 1 to 2 lbs of pellets per hour depending on the variables in play. That means that your fuel cost is somewhere around $1 to $2 per hour depending on how you buy pellets. I can afford cost of the smoker but I am not willing to pay $8 to $10 for fuel to smoke one pork butt at a time. Am I correct here or have I missed something. Most of you guys that have a 640 are smoking with the thing full or half full. Is that correct? I am disapointed because I really wanted to see a Yoder 640 on my patio but I don't think it would be a good investment for me because of the way that I would be using it. Sombody tell me that I am wrong so I can reconsider............
