Traeger and Hasty-Bake Grills

"I have been using a brinkman vertical charcoal smoker and the electric variety of the same smoker. My results have been good, but the quantity cooked at a given time is very limited. I have been thinking about stepping up to either a Traeger auger-driven smoker/grill or the hasty bake chacoal smoker/grill. They are both pricey, but I would not mind the money for a good quality product.

I assume the Traeger grill is extremely easy, and the closest to a true walk-away cooker, but what about the Hasty-Bake? It has been around for a long time, but is maintaining temperature any easier than with a weber smokey mountain? Does anyone have any experience with either the Traeger or Hasty-Bake cookers?"
