Right. The D7100 is a very good camera.
But if looking for a second workhorse "beater" camera, I very highly recommend going what it takes to obtain a moderately-used K-5 IIs and the DA 18-135mm in excellent condition. I have a number of the camera bodies suggested, and also this very useful, well-built lens. I find the K-5 IIs is tops by some margin. Its imaging qualities might come as a surprise for being "only" 16mp. For one thing, the "s" means it has no AA filter thus allowing greater fine detail in images. Dynamic range is exceptional. Build quality is excellent- a flagship design. Preservation of detail in low light or fast-action higher ISO use is exceptional.
Even highest-quality JPEGs right out of the camera are exceptional, just remember to adjust sharpening in the Custom Image menus, especially in the most-often used "Bright" category. With this 16mp sensor, you can increase sharpening by one more notch in the "Bright" category to +2 without unwanted side effects, then additionally also implement "Fine Sharpening" by using the rear thumb dial, to take full advantage of having no AA filter. For uniquely less-compressed JPEG images, the camera can be set beyond high-quality one more step up from 3 star to 4 star, providing very low-compression JPEG quality. Of course this means considerably larger file sizes, but closer to RAW.
