Interesting review Andrew, thanks. My thoughts are that it is an expensive item but, if it does what you need, is probably worth the outlay.
I don't do Lightweight and the Trangia is fine for me with a tiny gas stove and cylinder as a quick hot water option. The only real thing I don't like is the fact that you are restricted to a particular sized pot with the cone design. I suppose for the lightweight outback stuff that is okay but it would probably worry me a little. I assume that, in the outback and the West, carrying clean water is a big thing?
