best heat protection spray?

[Cinammoncake]

Can you recommend me a good but not expensive heat protection spray (to use with straightners or curling wand) thanks

Toni & Guy or 2b Guardian Angel.

The Lee Stafford one is really good and smells like sweets.

I've tried a few but usually end up coming back to Treseme (sp?).

Thanks going to take a look at all of these

Bumble and bumble cream is to die for. It's not cheap though

I use Wella Thermal Image, think it's about £7 per bottle on Amazon. Smells lovely!
