I am a happy user of the Emberlit Ti titanium wood burning stove which packs flat and weighs very little. Today they started a Kickstarter project for a smaller version which also has slots for a Trangia burner called the Emberlit FireAnt.
Kickstarter backers will get the stove at a very good price so if you are looking for a small wood stove, check it out.

Apart from titanium being light, it is also very fast to cool so when the fire is put out you can pack the stove together within a minute or two.
