These days, that kind of rice cooker looks like this:
These rice cookers can cost several hundred dollars. But I wasn't up to spending that kind of money.
I did a little bit of research on rice cookers. They say to make sure to get one that is nonstick and that has a removable pan so that you can clean it easily. I ended up buying this rice cooker:
It was only about $31 on Amazon and it's nice and small (holds 3 cups of rice). It got good ratings. I've used it quite a bit now and it's perfect.
It makes cooking the rice so easy. It comes with a cup measure. Then you don't have to measure the water. You just put the inside pan under the faucet and fill it to the appropriate mark on the inside wall which is based on how much rice you are cooking.
Then you just click the button and 20-30 minutes later you have perfectly cooked rice.
