D70, D80, D90, D7000 would be your best bet for prosumer bodies. D70 being oldest and D7000 being newest. If I was in the market for a new body it would be the D7000. Take it for what its worth cause its just my opinion. If money were no option I'd go for the D3x but it round up near $5000 just for the body. Hope this helps.
