All IMUSA pressure cookers are 11.6 psi.
I purchased one today and it did not have a cookbook. It did come with a little instruction book, though.
Some brands of Cappuccino machines that one can purchase from are DeLonghi, IMUSA, Melitta, Mr.Coffee, and Capresso. Most brands appear to offer low priced to high end priced models.
Granite Ware, Mainstays, IMUSA all sell this type of device and you can look here for some pricing information and if you are interested to purchase http://www.walmart.com/ip/20QT-TAMALE-SEAFOOD-STEAMER/13370050.
I found it! I have a 12 qt Mirro Pressure Canner/Cooker. Someone has downloaded the original instruction booklet in a PDF format online that includes the recipes. This booklet is for all Mirro Pressure Canners/Cookers. It's a 25 page booklet that would be best printed on both sides of the paper if you have that kind of printer. Don't worry about finding pages 4 & 5. They are blank anyway. Go to: http://www.pickyourown.org/canning_equipment/canner_manuals.htm Scroll down to "Mirro Pressure Canners and click on: "Click here for a Mirror Pressure canner manual." They spelled Mirro with a r but it's just a typo. Hope this helps!
