I can state for a fact they are nice smooth welds and clean easily.. I bought a 7.5 gal and use it as my secondary. It's friggin awesome. As something to condition or lager in long term nothing is better. Also fits into a standard refrigerator with out modifying the door or anything.
If they could make see-tru stainless steel it would be my primary. But I have to watch my Yeast make babies. So I still use a product no one makes anymore. But I find to be an awesome primary. http://www.homebrewtalk.com/reviews/early-mr-beer.html
If my only choices were between, the cavern, a carboy or a bucket.. Hands down it would be the Cavern.
