Right now, you can pick up a high end SS Brewing Technologies 7 gallon stainless steel conical fermenter for just $395!
These stainless steel conical fermenters are loaded with features and I personally have two of them, a 7 gallon and a 14 gallon. I also have 2 of their 7 gallon brew bucket stainless steel fermenters which are also great. In my opinion they are the best fermenters out there for the money. I would recommend upgrading the racking arm on the unit to the MoreBeer Racking Arm system which you can find here for $75 and is shown in the above image on my fermenter.
I cut down the legs in this 7 gallon conical fermenter so that it could fit in my fermentation chamber / chest freezer. My 14 gallon conical fermenter has an internal temperature control system. The 14 gallon unit is currently on sale for $495 and is available here.
