I've always had a rice cooker, as we eat rice every day.
We could eat rice for every meal, if we aren't watching our carbs smileys/smile.gif
Here's my thoughts.
The cheap $20.00 ones are fine if you are going to cook rice occasionally.
The cooker warmer ones (Tiger brand is the most common, about $100 to $150) are good if you are eating rice for more than one meal a day, or need to cook it it advance. I have one of those, and will keep rice in there for up to 24 hours.
The fuzzy logic ones, like the Zojirushi ones, are best if you cook different kinds of rice, especially brown rice, since there are different settings for the different types of rice.
I really don't like brown rice much, as it's drier and harder than white rice, but the sensible side of me keeps saying I need to do the whole grain thing. Hub likes brown rice, so I really should cook it more often. A friend swears by her zo, saying that brown rice comes out so much better in the fuzzy logic cooker.
when my Tiger breaks down, I'll probably get a fuzzy logic.
