We have a zojirushi that cost us $170 in 2002 and it still works great. I think they still sell the same one at Amazon for $199. It is terrific...it supposedly has "fuzzy logic" that allows it to figure out how to perfectly cook whatever is in it, and it always does. (Which is good, because I sure don't know what I'm doing, LOL!) It will also cook pilafs and other rice dishes like jambalaya. It automatically switches to the warmer setting when it's done, and will keep things warm for several hours. And it is teflon coated and cleans up easily. Although it was expensive, it was totally worth it: it's never made a bad batch of rice, we've had it for years and it still works great, and it's super convenient.
Sorry, I don't know if that helps too much since it's a pricey one, but it has really been worth the money considering how many years we've had it. (And DH was psyched that it is the same one they used on the Japanese Iron Chef!)
