At the risk of being redundant, Traegar Pellet Grills. Automatic, thermostatically-controlled, with the choice of several different flavors of wood pellets available. Fill the hopper with the pellets of your choice, plug it in, turn it on and set the temperature. No worries about keeping it at the right temperature or replenishing fuel. High-quality products with the option of smoking or grilling at temperatures up to around 425 or so. Not good for searing meats like a high-temperature grill, but it can do just about anything else.
