I've had a relatively cheap rice cooker for many years, and I hate the thing. I think I finally threw it out. It never made anything approximately close to decent rice, it burped white goopy water all over, and it frequently burned the rice on the bottom. The rice would turn out consistently bad, but in very different ways. I always measure with rice, and this cooker would produce wet sloppy rice one day, and dry crunchy rice the next!
It seems like everyone here is thrilled with their rice cookers. I'm amazed by that given how horrible my experience has been.
