If you are ever in the Iowa City area and have an extra 3 that I would be willing to sell. I bought these from Keg Connection and have cleaned them and inserted new rings. I paid $55 apiece and would sell for $45 apiece. I only needed to use these extra kegs once for brewing beer for a very large social function.
