I have cooked on Traeger commercials and backyard models. I have an FEC-100. I've also cooked on Country Smokers.
Country Smokers and Traegers are on par with each other in terms of final product. The Traegers are more expensive, but might be built a little better. If I were to buy again, it would be a Country Smoker because of value.
The FEC-100 uses much less fuel and is super easy to cook with. The vertical cooking is better for bigger meats. The Traegers and Country Smokers are more like Smoker/Grills. You manage them differently. On the FEC, I close the door and come back 10 hours later to wrap my briskets and butts. With the Traeger, I have to turn/flip everything because it cooks a little more direct.
Having said all of this, I know of a GREAT deal on a Traeger 150. It has two firepots and one controller. Lots of surface area and great for an at home or even comp cooker. You can grill and smoke on it. I think the current price is about half the new price and the guy is needing to get rid of it. Its a quality smoker and a great value. If that doesn't interest you and you want to buy new, check out the Country Smokers through
