Query: All-American 21-1/2 Quart Pressure Cooker

This is a great pressure cooker. All of the forums that I was browsing said All American pressure cookers are the best and I would have to agree. Amazon.com had it for the cheapest price and the delivery time was very quick. I have had no problems and look forward to many years of use.
