What's the best straightener?

i have a chi, but i'm starting to think that there HAS to be something better than this.





i havve medium-length fine hair (but lots of it). it's already straight, but i use a straightener to add style. what do you suggest? i really need something that makes hair shiny!














any suggestions?


thanks to all :)What's the best straightener?
GHD (:
