I am partial to
Smokin-it and Cookshack. But they are pricey. Good warranties and all stainless inside and out (less the racks on the Cookshack; stainless is an option). PS Seasonings makes a good smoker with a good reputation (PK 100 Pro) but I have no hands on with it. For a while, Cabella's re-branded the PK 100, if that means anything.
