Brand new, unlined, painted drum w/ lid and clamp is $55 at SW Container. These show a liner you will have to burn out then scrape, plus paint. Also, unk prior contents. To me, it was worth the extra $$ to not bother w/ a used drum. Saves a ton of time, expense, hassle, etc..... and building one w/o welding, easy as a ASU co-ed.
Great cookers and simple to maintain a temp.
