Im with the other guys, more so because I wouldn't buy old tech new. If your going to punt for a 7100 might as well get a used one because the 7200 is now out. I believe there was a big step up from the 7000 to the 7100 and a slight upgrade to the 7200. I shot with a D70 for a long time and then bought a used D90 body about 3 years ago. Video has never been something I have been interested in with a DSLR.
Looking further ahead though, do you want to invest in a DX body? To me it looks like Nikon is phasing out its pro/high end amateur DX bodies. The D7200 seems a little underwhelming to me so I sold all my Nikon gear to fund the Fuji XT1 and lenses. Same/better IQ in a smaller and lighter body. It was a big leap of faith, but Im sure I made the right decision.
