Thanks Lostbears.
I assume you are happy with yours? I have read some good user reviews, although most users seem to have to roll tubes to maximise it's potential. Nothing wrong with that mind you.
I have since found out that I can buy a unit with voltage set at 240v from a dealer here in Australia, I asked because there is a unit on ebay at the minute at a decent price, but it is also 120v. I may have purchased if it was switchable.
