Digital SLR Cameras | Nikon Digital Cameras | D-SLR Camera
These are the Ferrari's of cameras. Generally, they are cameras for professionals. Some of their lower end, high octane models will fall in your price range. I think the camera they push on consumers is the CoolPix model, of which they have a tradional digital camera (think college girl with a camera at a party) and something that looks a bit more practical.
Of the higher end model, this bad boys is solid.
