I was trying to post this earlier but kept getting “The server is too busy at the moment. Please try again later.”
Anyway, if I have the money I would go for the best. The D7000 is a great camera but currently there is a better one on the market, the D7100. We can all argue whether the difference in price is justifiable but I am sure we all agree that the D7100 is the better camera.
I still think that you should give lenses the first priority here, you will be changing and upgrading camera bodies while still have the same good glass.
If you have the cash then go for the D7100 with F2.8 zooms or F1.4/1.8 primes.
If you are on a budget then go for F2.8 zooms or F1.4/1.8 primes first, then a D7000 if you have any money left.
This is what I would do. Hope it helps
