I have a stainless steel rice cooker/steamer.
Here is the link: http://www.fernsnutrition.com/hmrice.html
(it is the one called "Miracle")
I love it, and it is so easy to clean, I don't know why anyone would need a "non-stick" one.
I came across it by accident (I was ordering something else from Fern's Nutrition) and had to have it, as I'd never seen a stainless steel one anywhere, even here in Japan where people eat rice for every meal.
