quit agonizing; just go for one or the other; after you get one you will want the other (or all 3); I've got a 85 1.4 and I really would like the 105 DC; I've been holding out and I where I once thought the 105 DC would be the ticket along side the 85 I can now see the trifecta (including the 135 DC) might really be solution
- but I might have to hold off on that until we see something like a D400 FF get introduced 
Oh Man!! I'm so tempted to get myself one of these too!
But I'm still tossing up between this and a 105(or 135) f/2 DC ????
