I was just checking NorCal Solution website and there is an option to add a gas in with pressure relief valve and a NPT male dip tube and thermowell for Speidels fermenters, i see Speidels fermenters as a big advantage over Keg with its size. I already have some Speidels fermenters so i will take a shot with these accessories and the close loop technique.
That'll make racking easier but those fermenters can't hold much pressure.
i think the corny makes a good fermenter for what it is.... a cheap, stainless, pressure capable vessel. It certainly has its flaws though.
