I have the model 921. Since I grow vegetables, I wanted to be able to preserve my crops and wanted something American made that doesn't use a rubber gasket. Think I paid around $220 several years ago, direct from the manufacturer.
I don't remember the capacity, but it holds a double stack of pint jars, where most other canners don't.
The All-American is made in Wisconsin, USA, from billet aluminum and uses no gasket. The only drawback is trying to get the lid off after a canning session. It requires prying with a small pry bar to break the seal.
I've also got a Presto pressure canner, but that requires the gasket to be replaced sometimes and it doesn't hold nearly the amount of the 921. Also, Presto is made in China. It's fine for the money and it does the job, but the quality just isn't there. It's much thinner and does not have a gauge.
The All-American canners look like industrial hardware and they are built like it.
