Have to say sorry, but a good friend of mine opened my thoughts for one detail on the 60x105 thing...
Having started on SLR photo with film (full-frame) and straight out to the 105 (which was a natural choice), I got so used to that, and so fond of super-macro that I might have missed one small (DX sized) detail.
On a DX sensor the 60mm is equivalent to a 90mm (very close to the 105 angle-of-view), and the 105 goes to more than 150mm, which is closer (just a bit) to the 200mm... Having said that:
I DO agree that the 60mm is a better lens to suggest for a new DX DSLR shooter.
