Query: Chi flat iron

I own a Chi hair straightener and absolutely love it !! I have had it for 15 months. My daughter wanted one of her own so I ordered it from Amazon Sept 2007 and January 2008 it stopped heating completely. 4 months old !! Amazon would/could not help me. I called Farouk and no help there. They can't guarantee unless purchased at a salon. We need another one to make the mornings easier and I am stumped as to which one to buy. Obviously I'll have to go to a beauty supply store and pay even bigger bucks!!
