I bought Fuji F30 recently - and I'm not disappointed a tiny bit! I like it for being small yet offering almost full manual controls and amazing low light performance. If you want a small advanced camera - this is the only one out there as of December 2006, and I have spent quite some time searching. An extra bonus is that it's got by far the best battery life out there - more than twice the average for this size.
Self-portrait of Fuji F30 mounted on a Joby Gorillapod - just as highly recommended as the camera itself - absolutely vital for good long-exposure shots.
