I just bought 4 of those on ebay. There going for $300 ea. or 4 for $1000.
There are some mods to be made since there not conical (draw off tube up for drawing off beer) but they seem to work awesome. First batch fermenting now. There labeled as 35 gal., But I think there at least 40 gal. Havent done a graduated test. Ill post some pics soon. Also they have cip balls in the lid which makes cleanup/sanitation a breeze.
