There's been more great food turned out on Traegers than any other pellet grill...mostly cuz they've been around so much longer. I've never owned a Traeger myself, but many who do say the build quality has suffered since production went overseas.
I wasn't familiar with that model...must be one of Traeger's newer lines. The free shipping is a very attractive offer. Plus, it looks like it's got some nicer features than a standard Lil' Tex or Traeger Jr., but for $750 there are other brands that might compete. Before you buy, you might compare: Firecraft, Green Mountain Grills, Louisiana Grills, Chargriller. And for a couple hundred more you could consider Rec Tec.
