If you plan on cooking rice a lot, definitely get a rice cooker.
Takes less than 1 minute to prepare the rice into the cooker and just set it and it's done.

I'd also recommend Thai rice for normal rice dishes, if you use the sticky rice for stuff other than what you want it tastes really bad IMO .

If you're now trying to make rice with the cooker don't add too much water, add less and when you cook it if it's too dry just add a little more water and re-cook it and it should be fine. If you add too much water from the start it's harder to save the rice it'll be all mushy.
