What size did you get? How many quarts will it hold?
I actually downsized and bought the 915 model... it holds 7 quarts or 10 pints... I found I never really stacked jars in my other unit so I figured no need to stack in the new one...
it is a interesting model in that it does not use a rubber gasket to seal.... it is all machined aluminum and is a metal to metal fit...
