I don't know anything about the Nikon line, but when I first started shooting a DSLR, I chose a Canon 20D because the EFS (white dot) lenses where much cheaper than what Nikon offered at the time. I shot with EFS lenses for a year and never much liked the results, other than the super wide 10-22mm which is outstanding. However, when paired with good glass, like the 70-200 F2.8 or the 16-35mm F2.8, that 20D did great. Most of the photos on my site are shot with that (nwoods.smugmug.com), certainly all the older pictures. I upgraded the body to a 7D two years ago to shoot video, but still use the same lenses, including a 10-22. But the key here is the glass. I spent over $4k on lenses to make the cheap camera body work well. I suspect the Nikon line will be similar. That's why I suggested the Canon G12 or newer. Same DSLR sensor, excellent metal body construction, decent speed and battery life, with built in good quality glass, and a fantastic LCD screen on the back. For a fraction of the cost, it will do what you need.
Here is a good comparison photo. This is Rock Creek near Mammoth, CA.
