I have used all kinds of rice cookers all my life and this is the best and most foolproof for Japanese/Korean style rice. Tips: 1) quality of rice matters--I get premium Japanese rice and while it's a bit more expensive, you can taste the difference; 2) Follow directions on the bag for best results; 3) Clean the parts to the cooker after every use. I believe it also cooks brown rice.
Another Zojirushi convert here - I have this model and love it love it love it. It's quite a bit cheaper ($60), very simple, and just works, every time. It's also a 10 cup cooker, so it can make a ton of rice. My wife and I usually make 2 cups at a time, but this is nice for when we have friends over. I will say that the nonstick coating on this cooker is different than any other i've ever used. Not the typical black teflon coating that will eventually end up in your food.
My family runs a Chinese restaurant. We've used Zojirushi for decades, and the name is constantly referred to as the best of the best.
I have a more basic model, a National SR-SH10RN, similar to this. It has lasted me about 15 years so far.
