I bought two of the blue 55g food grade (new) barrels here in Calgary. They have a removable lid but are completely air and water tight. The lid has two standard FPT fittings, so plumbing is easy. I forget what I paid, but I think it was something like $80 each.

I would trust these not to leak more than my tank.
