Can anyone recommend me some hair straighteners under the £40 mark please?!

[BupcakesAndHaunting]

My mum has said she'd quite like some for christmas. I'm on a budget of about £40. She has quite fine hair in a bob.

I have no idea what I'm looking for!

I have Babyliss Pro 230 radiance ones but can't find them in shops now.

However, Argos have some pro 235 ones at half price with really good reviews.

I have some Remington ones that my (ex hairdressing) sister recommended to me - I've chucked the box and it doesn't say anything other than Remington on the straightners but anyhow I bought them in Tesco last year for about £25 and they are really fab - they have some on their website at the moment that look the same
