Well, here are my updates on my purchases last month. After having 18-105 mm in my kitty, I purchased 70-300 mm Nikkor lens. This is quite good for wide tele shoot. But for macro photography I am still not satisfied... so I am planning to buy 105 mm macro lens from Nikon. The results from this lens looks pretty awesome and this is going to be my next purchase. Do post your results also.
