I was researching these fermenters recently. These are not conicals, and they are a lot cheaper too. Chapman makes a 7 gallon with or without a port that looks like a 3 piece ball valve. No pictures of the inside, so I'm not sure if it's a welded or weldless fitting. I'd be concerned with a weldless fitting both from a hygiene and leak risk. Not sure if it has a dip tube either. Anyone else have experience with non-conical stainless steel fermenters?
