Sorry I haven't been in touch, really busy at present. Right, in the end I decided to get the LX3! I saw pictures of both the G10 & LX3 and the LX3 is much better for my needs.
I haven't got a lot of time to try everything yet, but so far I'm really impressed with it. I really like the 24mm, and the picture quality is very good. I'll share my experiences with the camera when I've tried a few more things.
The Leica DLux4 carry case isn't available yet, but it looks a lot better than the Panasonic case, and has a better format. Not cheap, but a perfect fit for the LX3.
