They had the field to themselves for a few years, but the idea was too good to go unimitated, and with the digital age came the electronic controller that allowed Traegers and others to create a system that had a thermostat in the cooking chamber that would tell the fan and auger when to do their thing. Today there are more than a dozen manufacturers making increasingly sophisticated machines.
Most pellet smokers are wood-burning ovens: great for ribs, turkey, brisket, and pork shoulders, but not so great for grilling steaks and burgers. The FEC PG series was one of the first lines of pellet burners to offer a sear station, a cast iron cooking grate right over the fire pot where the wood pellets burn. It isn't the best setup for searing, but it's better than most other pellet searing schemes. The real beauty of the Fast Eddy's design is that it produces meat with a deep mahogany finish, much like a competition-grade offset smoker. It also has two upper-level heat zones, for a total of four distinct temperature zones.
