Which is the best ceramic hair straightener?

I have a Chi right now but it is getting old and the heating element isn't getting as hot as it used to. I was wondering if I should get another chi or is there something better.Which is the best ceramic hair straightener?
I have always wanted a Chi but couldn't afford it so I did research and was recommended to get a Andis. I got a 2 inch Andis from Ebay and am very happy with it so far. I have thick wavy hair and it used to take like an hour with a Vidal Sassoon iron. Now it takes me like 10mins for my whole head. I'd give it a try and if it doesn't work for you, i'd just get another Chi
