I still use the National rice cooker that I bought in 1976, to the consternation of my Japanese friends. What they don't know is that my son inherited his National rice cooker that my parents bought in 1967, and he is still using it too.
I've tried countless expensive and inexpensive rice cookers, including Zorushi, Sanyo, Cuckoo, both regular and pressure cooker models. The best I've found so far is a 10 cup Tiger brand cooker made in Japan. It is an induction cooker that has an eight layer pot and cost about $600. It's expensive, but quick, simple to operate, and produces perfect rice.
