Thanks for info erin - but I don't think the Babyliss one uses steam which I really need as I dry my hair first then curl the ends. I also like the cordless ones to take away with me.
I can still get my Braun smoothstyler on Ebay but as they are now discontinued the prices are getting higher and higher as people are cashing in! I have been able to still get the Braun (blue) canisters (4 for £7.50ish) from Boots and Wilkinsons but even they are getting scarce now.
