Thanks for the input everyone, I really appreciate it! I'll try to play the family card and talk him down a little bit more. I will more than likely purchase it.
I love my d90. Built in AF motor, Auto FP, dual command wheels. Never had issues or really outgrew it. The resolution of the newer cameras is great but unless you're cropping a lot, it doesn't make that much of a difference. I've done lots of paid work with it and used within its limits, it does well. If I need cleaner high ISO or faster AF, I just grab my d700. If you can get a good deal on it, Go for it. I have gotten good shots that I have printed up to around ISO 3200 but only a 4x6 ( for my enjoyment.)
