I use this for COOKING and it can't be beat.  Old Mirro gasket gave up the ghost and decided it was time for a new pot.  Never used a Presto before and was leery of having only one pressure setting, but it's okay.  Not crazy about the handle, but it does have two, and I've been very happy with it.  6 qt offers some added possibilities over 4 qt and corn is no longer a problem.  Got stainless for the price of aluminum.  Can't be beat.
