John, I'm selling quite a few things at the moment, partly to raise cash and partly to declutter the place. I do think the LX3 is a great point and shoot camera with a very good lens. The F8 minimum aperture is a bit limiting but the F2 maximum aperture is excellent in that type of camera, making it very usable in low light without having to go to ridiculous ISO numbers. If I ever need anything better in low light, I have the D3 and an F1.2 lens anyway.
Markt, I may well sell the Viewfinder, but probably to go with the GRD2 if I decide to sell it. It is quite handy that it fits on two cameras though.
Cesare, absolutely the GX680 at around 4kg with lens, battery and AE finder is easily used for exactly the same job as the LX3.
Biggus-Dickkus, the zoom is limited to maximuse the aperture. If you need longer telephoto lens capability Panasonic do make other Lumixes but you'll be shooting at F5.6 or so.
