These are the Update International pots - I linked to them earlier in 100qt version but you can get the 80qt's for about 160 bucks per with free shipping from instawares. Note that kit only includes 2 pots. For 480 you could have 3 pots, then another 100 for the FB, valves are cheap (get them from bobby_m), then the only thing not accounted for is couplings which you'll probably want to get then have welded in. So for a few more bucks, you get an extra pot out of it and then you can setup the couplings however you want.
