I have only seen it in catalogs. Sorry I can't help. Do they just make pressure cookers and the risotto cooker? I was tempted several times to buy one when my pressure cooker was acting up but I still haven't gotten around to it.
I use mine at least once a week. It's wonderful. You can get depth of flavor in a soup or stew in a very short time and you don't lose the nutrition. Highly recomended. Thicken your broth or gravy after cooking so it won't stick. Your liquid will be so hot when you open the cooker that you can just pour in your slurry and stir and it will thicken almost immediately.
Kuhn Rikon is very safe, too. It has several steam releases as back ups.
