Home Steam cleaner, Australia

[heyyoumob]

Any Australian PS users have a recommended home steam cleaning unit? If so, where would I get one from?
Think it would make a nice Christmas pressy for the missus.

Think I'l get one of these, and as a bonus I can use it to clean my BBQ!

Do I have to be careful with too much steam pressure? figure I just hold the jewellery far enough away to get the steam wiothout blasting it too much.
