I know a place that has 55 gal. closed head stainless drums for sale for $55. He has quite a few, many have small dents, but I'm sure most will push out from the inside. He has a bunch so you might find some that have no dents. They are all stacked inside a storage shipping crate. They held dilimolene, which is a citrus based product. I am just passing along the deal - not interested in trying to make money off of this, so I will not ship.
