Best M4/3 combo

Guys,

could you reccomend me a best M4/3 combo. I've used P&S and DSLR's. The first are too weak in low light, and the later too big and cumbersome.

So, I need a small camera with the lens that performs well in low light. Zoom is not very important, I will use my feet The first big test will be a trip in June to my friend's wedding in Switzerland.

Thanks in advance

Neven
