Which straightener should I buy?

I am thinking about buying a new straightener, but I can't decide which one I want to get. I really like the CHI Mini 1 1/4 Inch Ceramic Travel Flat Iron and the Andis Ceramic Clamp Flat Iron! I've tried both of them out and I can't really decide which one I like the best. The Andis straightener is about $20 or so and the CHI is about $50. They aren't much different, but I just ume to go ahead and go with the more expensive one if I am going to purchase a new straightener. Which one do you think I should buy? Thanks! (:
