Consumer-level Traeger grills are considered a mid-range type of pellet grill, so they’re good for those wanting to try pellet grills for the first time. Traeger models like the Lil’ Tex Elite 22 or the Tailgater cost several hundred dollars and can grill about 12 to 16 burgers at a time. Larger Traeger grills will generally carry low four-figure prices, such as the Pro Series 34 or the Select Pro, which can hold 32 to 40 burgers between the upper and lower grilling racks.
To start using the grill, pour wood pellets into a hopper (pellets are usually are made from compressed sawdust). Press the start button to ignite the pellets, which are fed into the fire box with an auger, where a controlled number of pellets are lit and burned (depending on the temperature setting selected). The auger adjusts the number of pellets entering the fire box to maintain the desired temperature.
I bought this directly from Traeger. Beware that this model is now discontinued. They replaced it with the Traeger Renegade Pro without notice. The new model has an updated saw horse design and a new digital controller with probes. It does not come with the handy spice rack however. To each their own but I'd check with Traeger prior to purchase. That said, I paid more from them so if this is discounted, grab it. I love mine!
****Update 12/2014: So I finally found something negative to report. Today I was cooking 2 pork butts and a brisket and discovered that this grill does not do well with wind on a brisk day (It was 45 degrees here today). When set at 250 degree, the smoker could barely make it up to 190 degrees. I was able to bypass the problem by throwing a cheap moving blanket over the grill (an $8 fix) but I think it's worth noting.
Although these are marketed as grills, they do much more, including baking or roasting. Because they heat by convection, you might not get the grill marks that a gas or charcoal grill will give you, but you also won’t have the flame-up problems. While many pellet grills offer high cooking temperatures, the maximum depends on ambient temperature and wind. Many users wrap their grills in special insulating covers to help maintain heat, reduce fuel use, and reach the higher temperatures they desire.
