I have a Ion straightener that died on my this morning. I last about six years!! So, now I am on the market for a new straightener. Thinking about a Chi. Are they really worth it, and if so why?? Thanks.

The helen of troy hair straightener is on sale for 30 dollars and its a $119.99 value i m just wondering if its any good or any better than a CHI hair straightener, they are both almost the same price regular price of course but the helen of troy one is on sale for 30 dollars.. anyone know ? should i get it? oh and its a 1" ceramic flat iron .. any advice on whether or not its good to buy?
