I agree with @Dan-Cope, you’ll be much better off to spend $800 on a D7200 and spend the rest of your budget on good glass. Adorama has a deal right now for $769.95 for the D7200 body only (Refurbished).
Is your kit lens just the 18-55mm lens? If so, you’ll definitely want to find a more high-quality lens, like the Nikon 18-140mm for all-around use.
If you’re going to be using your new camera for product photography, I would also highly recommend the “nifty fifty” Nikon 50mm f/1.8 lens.
