D700 and Macro len
Since you are comfortable using manual focus non-CPU lenses, you might also consider the 105mm f/2.8 AIS. It's rather well regarded and can be had at reasonable cost. The extra length will give you a little more working distance; especially useful for twitchy insects with mean temperaments.
