Another vote for the G2, I have my gripes but on the whole a fun camera, excellent lenses. I do have concerns about the future of serviceability, but it's cheap enough that you can get a few bodies if you really love it.
How much is "cheap enough"? I've been monitoring auctions of G2 bodies, and it seems that the going rate is usually over $500 for used bodies. And it seems like prices are rising recently!
