Thanks for the advice so far.
Since the internet took over the world I've been awoken to (and aghast at) the effects of zone marketing.
Some regions (Europe, Australia etc) are simply being ripped off for a broad range of products, so where possible I try to get around this (buying online).
Of course this is not always possible or practical - especially when you plug it into the wall.
As for the Triton - I supose I am leaning toward the Hitachi since it has a loyal following over a long period of time - tried and trusted.
But since I have to buy locally, I may re-assess the situation before shelling out 500 AUD for something that costs 220 AUD elsewhere.
Stephen.
