Got an e-mail from bodycare2000.com offering a free 'upgrade' from GHD IV classic to the limited edition black gloss version. These go for AUD$239 in the hair salons. http://www.ghdhair.com/au/limited-edition-ghds/ghd-black-glo…
I bought a Cloud-Nine straightener for my GF from this site recently. Service was pretty good, delivered in 16 days. The Cloud-Nines are as good as if not better than the GHDs. And yes, these expensive straighteners are better than the cheap $30 K-mart ones. My GF had a cheap one and it didn't slide as smoothly nor did it get her hair as polished.
edit: Comes with a UK plug. There's an option to include an AU adapter for 1 pound extra.
Might want to mention that this will have a UK plug, so you will need an adapter.
