No offense meant here, and I honestly don't care if someone purchases a tank from that link, but that isn't exactly an apples-to-apples comparison. Here is the original tank: http://www.plastic-mart.com/class.php?item=138
. Besides being a different brand tank, you aren't factoring in shipping nor the price of the SS dump valve fittings, casters, and insulation. I know from when I purchased these, it would be hard to get away with one tank for under $250 by the time shipping was added in. On top of that, a 2" stainless ball valve on McMaster alone is just under $150.
Anyway, my purpose of the post is to maybe help someone out locally (nano startup ?). If not, I'll just keep putting beer in them.
