Which camera wouold be best for me?

I'm wanting a new camera, I own a Fuji Film s2500hd and am lookign to upgrade with a camer with changeable lenses. I have found three I like the sound of Panasonic Lumix DMC-G2, Panasonic Lumix G10 and the Nikon D3000. I like the look of them all, the fell and the price is just right for me. I was just wondering what someone who knows more about cameras then me thought.

I'd go with the Nikon.

Nikon of the two has the most available lenses, both new and used.

Here is a site that discusses all different makers of dSLR cameras. That knowledge will help you pick your eventual camera system. What people moving from a P&S camera to a dSLR usually do not realize is that once you pick a Nikon or Panasonic camera, you are going to have to live with that system for a few decades.
