I had a housemate a few years back who had a quality rice cooker with a hinged lid. He'd make a large batch of rice and it kept warm and moist for days. I ate a lot more rice back then and it made making dinner much faster and easier.
After my housemate moved out, my parents bought be a rice cooker for Christmas, but it's the kind with a glass lid. The rice dries out very quickly, so you can only make a small batch at a time, and it doesn't make small batches very well. I eat very little rice now because it's such a bother to make and because leftover rice dries out in the fridge. I'm thinking of buying myself a rice cooker like the one my former housemate had. Some of them have timers so you can set it up in the morning and come home to have perfectly cooked rice waiting for you.
Unfortunately, I have very limited counter space in my kitchen, so if I buy a new one and start using it a lot, I'm not sure where I'm going to put it.
