I have followed this thread with interest! I bought the Nikon 105 F2.8 Micro G. I purchased it new and it is a wonderful lens. I find myself using my 70-200 F2.8 VR2 more frequently for portrait work though.
 It has some CA in very trying conditions but I rate the 105 very highly.

 I am very pleased you obtained a nice 105D. That lens has a great reputation and I think you should find yourself enjoying it a lot!

 I have only purchased 1 lens used, my VR2. It was unused in open box and costly but less than grey market here in America. It is a very nice lens. I find buying them new an efficient way of rapidly decreasing my bank account.

 I really want a 200F2 and a 300F2.8. But I won't buy them. I know I would use them so little it would be a huge waste of money. But they are sublime.

 I bought a 200-500 F5.6....up to 400mm and slightly more not bad. No hotshot at 500 though.
  I will try shooting the moon with it tonight and see how it fares.

 Best wishes and happy shooting!!!
