The rice cooker is easiest, but there's another scheme: use an abundance of water and cook the rice like spaghetti. I learned the technique from a Lynne Rossetto Kasper cookbook, and it's never failed me.
I had never heard of cooking rice like pasta before. (going to try it next time I cook rice, thanks!) I think this is a good example of a small piece of knowledge that can possibly have a larger effect.
