I have had my traeger for 10 years. I can't say I've ever had a bad meal on it. I've done almost every recipe in their book and a bunch of others. From a brisket I did that took about 11 1/2 hours, to a 20 minute Papa Murphy's take and bake pizza, you really can't go wrong. I've had gas, charcoal grills in the past. They really can't compare. To make the Traegering i.e. grilling easy and foolproof get yourself a digital remote thermometer and receiver.
I have a buddy with a green mountain and it's very nice too. You really can't go wrong.
