Hair Straighteners

So I had my hair cut yesterday, and my lovely hairdresser used GHDs to do pretty things (hairdressers always get excited by my hair and always end up asking me if they can do something fun with it at the end ... it adds on an extra 45 minutes but costs me nothing so I say yes). Having GHDs used on my hair made me remember how utterly rubbish the straighteners I own (but rarely use) are.

I can't really afford any but I was just wondering what straighteners you ladies use, and if you think that there's anything that can beat the might GHDs?

Interestingly, my hairdressers were sent Cloud Nine straighteners but didn't really rate them against GHDs - I know that a lot of you ladies have been sent them to try, what did you think?
