I have one drum option. It's the best price/proximity for me. It's unlined and new so I'm doing it. The lid as I said is flat, no bung.
I don't want to use my kettle lid in it because of how nasty smoking makes the lid. I used to smoke in my 22 in kettle. Nasty. Down the road if I can find a Craigslist lid sure but now I'm focused on the flat lid.
So it looks like 2 votes for a stack so far.
