HELP! Are CHI hair straighteners really worth the money? Do they last and work for a very long time?

I straighten my hair everyday. If I don't it just looks bad. I have used a CHI before (not owning it just borrowing one) and they are amazing. They are on sale at for $94, the original price is $150. Should I do it? I know they do a great job, but if I am going to spend this kind of money I want it to last. Does it have a warranty?
