One more vote for the Chi. I've owned about 4 flat irons thinking the cheaper ceramic ones would work but the Chi just works SOOO much better. Be careful to use products to protect your hair (like flat iron spray)before you use it. Also, the smaller the "chunks" of hair you straighten at a time, the better it will look. If you try and grab too much hair to iron, it ends up looking very flat and won't move as well.
