The popular Traeger Junior Elite is a great smoker for first-time chefs as well as experienced smokers who are short on space. It's versatile and can grill, smoke, bake, roast, braise, and barbecue food. The digital controller is adjustable to +/- 20 degrees and has 300 square inches of grilling space that is large enough for two whole chickens or three racks of ribs.
The Yoder YS640 is 32 inches wide, weighs 313 pounds, and is said to have a cooking range of 150 to 600°F (65 to 315°C). Yoder is known for heavy-duty competition smokers, and the thick, 10-gauge-steel cooking chamber on this model is durable and great for heat retention. It comes with a sophisticated proprietary digital controller, which Yoder asserts is not based on any off-the-shelf temperature controller of any sort. Yoder states that it designed the board from scratch around a general-purpose micro-controller chip and wrote its own code from the ground up in an attempt to provide superior flexibility, efficiency, and accuracy.
To your question regarding Traeger, I’ve not reviewed their grills of yet. I do know that Traeger as a company is taking steps to up their game some, as quality/reliability of their pellet grills has diminished over the last few years. The new CEO – Jeremy Andrus – they hired comes from the Skull Candy company and brought that headphone company from annual sales from less than $1 million to nearly $300 million. I know also that a few big hitters in the BBQ world are being contacted by Traeger to bring the brand back to its former prominence. You can read more about that here from the site of one of the company’s that now has an ownership interest in Traeger: http://www.trilantic.com/News_Story.aspx?StoryType=1&ID=56.
While many people enjoy pellet grills, some find it difficult to use pellets to produce true, flavorful steaks and barbecue since the fuel often lacks the same flavors as traditional grills. That smoky, wood flavor many steaks have is not impossible to get with the right pellet grill however. The Z Grills Wood Pellet Grill sports a combined grill/smoker setup with temperature control for the best pellet grilling experience available.
