I bought and love my Nikon 105mm micro D lens, but I loved my old 105mm micro converted to ai too! So I would say something from 90mm to 105mm micro lens would work very well for ya! 
If I was rich I'd collect macro lenses! I love them, and how great they can be for non-macro shots too! Awesome lenses!
