There were some good threads on camera choices a while back. You might want to try a search. Try this thread:

In the end, it all comes down to your price range, the type of pictures you're planning on taking and where you'll carry your camera. I use a mid-size camera, the Canon IS3 because I want the features (zoom, stabilizer, view finder, macro, etc.).

However, it is too big for in my pocket and I find the rear rack bag too inconvenient. So when I travelling and want pictures I have use the smallest Topeak handle bar bag. Enough padding, enough room, but not too big and heavy to be terribly detrimental for my riding. Others would feel differently and never use a handlebar bag.

Have fun shopping for one...cameras are almost as much fun to shop for as bikes! (well, I think so )
