I think some posts are mixing the Cookshack product line. Cookshack makes residential, competition, and commercial equipment, in the form of smokers, charbroilers, and one combo unit.
The Cookshack smokers are electric or gas fired smokers that use a small amount of wood for flavor. These are available in residential or commercial versions, but not competition due to the fuel source.
The "Fast Eddy's by Cookshack" are pellet fired smokers that are suitable for competition or commerial environments. (It's one of the few pellet cookers that is NSF Certified.)
Both of the above lines are smokers - suitable for bbq but not hot enough for grilling. The Fast Eddy and the commerical smokers can be used indoors or a trailer with external venting - they have a place to attach an exhaust vent pipe.
The charbroiler is a relatively new addition to the line. It uses the same kind of technology as the pellet smokers, so it's completely wood fired. Since it's direct heat, it's suitable for grilling but not for BBQ. It's intended for commerical use, but would work for residential or competition situations as well with the optional lid. To use indoors or in a trailer, you would need a smoke hood since there is no vent pipe.
Cookshack also introduced a Fast Eddy grill this fall. It has direct and indirect pellet heat, so you and grill and bbq on it. It's really intended for residental use where people would like to grill and bbq and not buy two devices.
I own a Fast Eddy's pellet smoker, and I have just ordered the charbroiler for my competition BBQ team. I can't speak for the charbroiler yet, but my smoker operating cost is much lower than comparable gas or charcoal fired smokers I have used. It will run for a weekend on $10 worth of pellets.
If you purchase pellets in bulk the cost per pound is quite low. BBQ's Delight will ship food grade pellets in bulk. The fuel pellets are a blend of oak and a "flavor wood" such as hickey, apple, etc. (Do not use heat stove pellets. Food grade pellets have been prepared with food safe equipment and lubricants.)
