Thanks for all the input.
I eventually went for a Clas Ohlson meths stove. It's lighter and smaller (though the frying pan/plate/lid is actually broader than the lid on the Trangia 27. The best bit is the price.
£9.99 from the clas Ohlson store (though unfortunately, if you don't live near one, they don;t sell online:

Here's a rundown on another forum against a trangia:

My Clas Ohlsen boils water quicker than my Trangia 25, but only by about a minute.
I also made a wood gas stove, just for fun, and it works well, and while not bulky itself is perhaps too much to take with the Clas Ohlsen as well.
I did find this though, which is ideal for burning wood with either a Clas Ohlsen or a Trangia. It's the Trangia version of the clickstand and about £20.

Being stainless steel, you could burn wood in it without it deforming.
