Traeger Pros and Cons:
Pro: Wood Fired BBQ, Grill, and Convection Oven. Makes a frozen pizza taste artisan!
The controller is awful. An aftermarket PID controller such as a Savannah Stoker is a must! I hated my Traeger until I got a SS.
Thin steel and not insulated. An insulating blanket is a must to conserve pellets
Not enough smoke flavor which is a common complaint with wood pellet grills. Solution to this is to install a Big Daddy Cold Smoke generator which does what it is supposed to do...its makes food magically delicious.
If you can afford it consider a Fast Eddy, Yoder or a Louisiana grill. They are better made than a Traeger.
BTW, I own a Traeger and didn't know much about pellet grills then. The Savannah Stoker and Big Daddy Cold Smoke Generator made it functional.
