I am OP. I just ordered this foldable titanium stove from aliexpress - £100 ($130?). It weighs 4.3lbs and packs into a small carry box. The skinny legs initially put me off but after looking through some reviews there are guys who have built/photo'd it and given it 5 stars, so I will see how sturdy it is when it gets here.

It's less than half the price of other titanium stoves, the same price as a heavy stainless steel one so I took a gamble. Will post results.
