Yup, i've purchased 2 drums thru their Tucson office. SW container is the way to go. I've purchased one bung lid and one non-bung lid. Depending on your ventialtion plan, either may work, but they are the best and cheapest you'll find. The paint also seems to stay on, unless to get a roaring fire. I don't do real hot burns, so as long as i'm just smoking, they look just fine!
Keep us updated on your UDS build, we love to see'em here!
