Portability Even if you never take your pellet grill on a road trip, you might want to move it from one side of the yard to the other when you’re having a party, or move it out of the way when you’re not using it. While some pellet grills are light enough to pick up and carry, wheels make the job easier. Of course, if you have a permanent spot for your grill, portability is less of a consideration.

The original Traeger Grill was invented 30 years ago and was every bit as impressive then as it is now. Although it developed a cult following, the early Traeger never grew beyond a niche product. In the past two years, however, Traeger has stepped up its game, redesigning and upgrading its grills while doing everything it can to build a buzz around its amazing do-everything cookers.
****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.
There is a bit of a learning curve when cooking with pellet grills. This unit can smoke, grill or bake similar to an oven. The Traeger smokes at 180*, but can cook up to 450*. It is indirect heat, so you can grill a ribeye without flare ups. My unit holds temps within 5+/- of the setting. Yes, you do have to clean it like a fireplace, it doesn't run on gas. The build quality is amazing, especially for a PRC manufacture. If you are interested in a pellet grill, buy a pellet cookbook. Something that gives smoke and cook times for an easier introduction into pellet cooking. The only knock against the unit is that for $800 it should have came with the "optional" folding shelf...
Pellet grills preheat quickly, so you can start cooking almost immediately, and the pellets are available in a number of woods, for different smoke flavors. The smoke has a subtle wood-fired flavor with less of the acrid flavor that comes from standard wood or charcoal. For the maximum smoke flavor, it’s best to cook at a temperature lower than 250 degrees, while higher temperatures cook faster with less smoke.
