Whats the best brand of hair straightener?

!!! i need to know! :DWhats the best brand of hair straightener?
Sally's Beauty Supply sells these straighteners, I believe the brand name's called GVP, but it's just Sally's store-brand. Anyways, they're like... $60, I think? And they come in loads of different colors. Those are great. I've talked to a lot of professional stylists about it, and they all say that they work just as well as a CHI iron, for half the price. :]Whats the best brand of hair straightener?
I have a CHI and i love it! i noticed the difference right away, compared to the old cheap straighteners i used to use.
i have a conair and i love it i as around $50 which isn't bad but not too cheap it work really well
