I need the best flat iron I can afford

I have heard that the best flat irons are the ones that stylists use in the salon.  Having a CHI sounds like a great thing but I’m not sure I could afford one.  That is the kind my stylist uses, at least, and I thought they cost over a hundred dollars.  Does anyone know if there is a comparable flat iron that is less expensive?  I am not sure there is because my hair always looks amazing when I leave the salon and I can never seem to achieve the same look at home.  I think it has to do with my tools.  With my problem hair, I think it’s time I invest in the best flat iron on the market.
