I'd go with the D3000, I have had it since the early spring and I haven't had a problem with it. I have 3 lenses for it, an 18-55mm that came with it, the 55-200mm, and a 35mm that I use for low light shooting. If your new to the DSLR game, it's a great camera to start with. I almost got the D5000 but I don't need to have vedio on the camera. If your going to do video, do it right and get a real video camera.
if you want some examples of photos taken with a D3000, follow the link to my flickr. Everything has been shot with a D3000 except for a few very old ones taken with a P&S.
