I have the D5300 and upgraded to get it with the 18-140mm zoom lens. It's a crop-sensor camera so the lens is a 27-210mm equivalent. That range is really very versatile as is the camera. Still photos and HD video with good range in ISO, speed, etc.
It does require lenses with their own focus motor (-S) in the name. The live view screen can be rotated so the camera can be held in different places to get a good shot. You can hold it high or low or frame the shot when you're standing in front of the camera. I also like it that the sensor for the wireless trigger is front and back, not just in the front like a D80 and others.
The D7100 is a bit more expensive and has different features, like a built in focus motor, but the same sensor inside.
