Traeger Grills offers something for everyone; they have portable; they have four different levels of Smokers in two different sizes. The entry-level line is the Elite good for someone on a budget and wants good quality. The second level is the PRO Series 575, and PRO 780 offers more cooking space and Wifi. The third level is the Ironwood Series 650 and 885. This line of a pellet grill is insulated in everything, but the lid offers more cooking and rack space. You would think that would be enough, but this grill gets hotter then the other two lower-level models giving you the ability to truly grill. Now the best for last, the Timberline Series the 850 and 1300. This grill is the heavest grill they make, and it is fully insulated, has three adjustable racks for cooking and a built-in pellet sensor.
