Query: Terrible!

Every time I've tried to cook rice in this thing, it boils over several times, makes a huge mess on the counter, and makes poor rice. I've only tried this with standard white rice, but it's always a little crunchy, and the boiling over is ridiculous. I tried every troubleshooting suggestion in the instruction manual, but nothing worked. Now I'm saving up for a Zojirushi.
