Rolling hair iron or flat hair iron?

I've been let down a lot by most flat hair irons and think they're really expensive. Has anyone tried this rolling one InStyler (http://www.instylerhair.com/) and have some thoughts about whether I could do the trial run?Rolling hair iron or flat hair iron?
I recommend the chi. it makes my naturally wavy hair pin straight.





You can find it for $99.99, but I've had my straightner for 4 years. If you count that you would have to buy 4-5 crummy straightners in that time it is pretty much worth it.Rolling hair iron or flat hair iron?
