You can get really simple ones that just work and due to little components they will last a while. IMO they're really worth it if you cook rice often or can't for the love of god not mess it up while cooking. They're really cheap as well.
I recently bought a zojirushi rice cooker because of their reputation for making perfect rice and lasting decades. So it's the AK of rice cookers. Or more like the AR because it was $200.
