If it were me I would be looking at the new Olympus 520. The in camera image stabilization is a great feature to low light, indoor situations. Also the new 28mm pancake lens would be wide. You also would be getting 10 MP images. The 520 just has more features and is more versitale. I think you should compare specs. You might even could swing for an E3?
I have read great things about the L1 but if you want IS you have to buy the lenses with it built in and it can get costly.
