Leica V-lux 2
If u have a Dlux 5 then you will love the Vlux 2, it has the zoom resources that you don't have with the former. I have a dlux 4 and now I bought a V lux 2, the experience is great. If you like to travel then this is the camera. I consider a M a better choice but not for the moment, only for the far future. If don't want to spend too much I would suggest the Panasonic Lumix DMC FZ100 it is the same camera.
