I lease from keg logistics, you get brand new Franke kegs. I went with slim 1/4's and 1/2's about $100 a month per 30 kegs. * year end of term cost is about 3 times buying out right. The thing that sold me is it is not exclusive, I can own my own kegs, If I find a good deal on something I trust.
I got a bunch of chinese kegs from a local refurbisher sitting in my hallway that won't hold pressure. Maybe I can sell them as boil kettles with no ba juju.
