Without breaking the bank, I'd suggest either a D7200 if you want to stay with DX format, or a D750 if you want to move up to FX (Full Frame). Other items may be just as good, or even better in some ways, but would probably cost more. Shop around, and consider buying a used, refurbished, item. I have both a D7200, and a D750, and I have no regrets concerning either of them. Let us know what you decide.
You beat me to it, this was pretty much EXACTLY what I was going to say.
