I've just joined the forum and hope that my contribution may be of some help in your decision - if its not too late.
I recently bought a V-Lux 1 as a back up and can tell you that I am very pleased with the camera and lens (especially the lens). However, I only use it at ISO 100 (occasionally 200), no higher due to noise issues.
Here are some samples I've uploaded for public view:

It is a super camera and fun to use, but I prefer the Digilux 3...... (however....I still prefer an M6 and film).
