While there's not a lot to dislike about pellet smokers, it really comes down to your cooking/grilling style.  Some Smoking Geeks prefer pellet smokers to traditional smokers (or even the Green Egg style smokers) testifying that flavor is superior to that of other styles of smokers within the price range – and it's hard to argue with them.   While Traeger is the pioneer, there are other brands that give it a run for its money.
****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.
First off, in general I was a huge Traeger fan due to my brother-in-law smoking up meat and fish for us for the past 3 years and it was just damn delicious. He also just raved about his Traeger, so finally I took the plunge and purchased a Century 34 model during one their Costco road shows. Customer Service - In general I will give them 4 stars because I am talking with a human, they were seemingly very thorough when I spoke with them and didn't appear to be reading from a knowledge base article when I described the problems. I also grilled them to ensure that the Costco specific model wasn't being manufactured with subpar parts since the price was so much less than retail and seemingly more bells and whistles. More than one representative confirmed that was not the case. This is where it stops being good news.
Wood pellet grills look like standard barbecue grills but some with a separate firebox for making smoked meats that will also let you smoke vegetables and other ingredients. As Traeger and Pit Boss both get good reviews from customers, it’s important that you look at the top features of this grills and how each company compares in relation to those features.
***Update: 11/2014: It's been a year now and I still adore this little grill. I've got a kamado and 3 different kettles and this is by far the most convenient and easy to use. The smoke rings this guy puts on a brisket are amazing and the flavor is the perfect balance of wood flavor without overpowering the meat. I've researched about 15 different pellet grills and I still can't find a better value than what this grill offers
But even with their indirect heat, wood pellets do something gas can’t; they give your meat that natural, smoky flavor you expect from wood. They don’t create as much smoke as wood or charcoal, so the flavor is not as intense, you swap that intensity for convenient cooking. The smoke they do create is clean and easy to control. And the hotter you burn pellets, the cleaner they burn, letting you crank up the heat when you don’t need smoke.
The smoker does not hold temperature. I called the service dept and they sent a new controller card and it does not hold temp either. When I contacted the service dept they told me that the grills do not hold temp at the 225 degree setting. If you look at all the Traeger literature and cookbook and recipes all say to smoke at 225. As does every other smoking cookbook. So Traeger manufactures and sells a known defective product. DO NOT BUY TRAEGER.
