Check out Lexington Container Company, their prices on metal Jerry Cans seem to be a little better than the price you quote earlier. http://www.lexingtoncontainercompany.com/Nato-Jerry-Cans.html
Those look nice. I wonder if they would do a group purchase/volume discount. Would any of you guys be up for it? If so, I'll talk to them and see if we can get a discount on some.
