If you're into "do-it-yourself" homebrew projects why don't you visit some local dairies and see if they have any old stainless steel dairy equipment laying about that they'd be willing to sell cheap (or maybe give you free). There's lots of overlap in dairy/brewery equipment, like tanks, kettles, whirlpools, etc. You could easily adapt this stuff into one kick-a$$ home brewery. Of course you'd have to brew 100 gallon batches.
