We have a Panasonic one the wife carted back last time she went home. It's handy in that you can cook some rice up and you have it available when you need and you can have some ready for breakfast. By the time you've farted around washing the rice, it's not any easier.
No idea mate, she insists on washing all rice until there's no more cloudy water. Think we have Nishiki usually, comes in 10kg bags.
