I found some real nice 9.2 gallon tanks (kegs) while browsing on Ebay. They look to be in real brand new shape and reasonable for $125. There are 10 of them available. Here is the URL if you are interested:http://cgi.ebay.com/Stainless-Steel-Tank-for-Biotech-beer-wine-making-35L_W0QQitemZ290407571595QQcmdZViewItemQQptZLH_Def aultDomain_0?hash=item439da3e08b

That actually looks like it's setup to be a beer line cleaning tank. I believe micromatic sells something like that in a 3 gallon setup.
