Long story short, we bought a bunch of stuff we didn't need. We have the following tanks, all unused (we actually washed them, but never put juice in):

500 gallon cone bottom (http://www.plastic-mart.com/item.aspx?id=183)

500 gallon vertical (http://www.plastic-mart.com/item.aspx?id=664)

(2) 1000 gallon vertical (http://www.plastic-mart.com/item.aspx?id=732)

Prices will be cheaper than new, and you do NOT want to deal with the plastic tank companies, they are atrocious to deal with.
