the pot did seem sturdy enough, But I never put a ball valve in it. I sold it a while back, so I can't look at it now, but I'd venture to say that it would work with a weldless bulkhead set-up.
hindsight is 20-20 I've got a stainless keggle now, I cut it myself, and put in my own ball valve with parts from mcmaster carr. I would never have got the 82qt if i new the keg was coming along ( laid out 160 for the 82) got about 35 into the keggle.
if you've got the tools or have friends that do, the keg is the way to go.
a friend of mine got mine at a swap meet for 20 bucks.
