Can anybody recommend straighteners that also curl hair please?

[Moonrocks6]

I had a pair of Nicky Clarke curl and smooth straighteners that were great for curling as well as straightening hair. They have had it though so I've bought a new pair but they don't get hot enough on the back to curl hair.
Can anyone recommend a pair that will do both without going to the expense of ghds please?

Diva straighteners

I have Diva Genisis ones and they are amazing

They look really good Derek but are out of price range really. I would prefer not to spend more than £50.
Especially as my sister has asked for some for Christmas too.
Thanks though

What about one of this straightening brushes that can curl too?

I hadn't thought of those. Will have a look at them. I have stupidly thick hair though so they may not be ideal.
I'd just like some similar to my Nicky Clarke ones but they don't seem to make them anymore.

You can curl hair with any slim straighteners. I use boots cheapies to curl my hair.

The babylis sines that I bought don't work.
