Legacy lens on NEX7

I have been bitten by the legacy lens bug since acquiring a 135 2.8 and 50 1.7 a few weeks ago. Since Sony is taking forever to release new lenses I have decided to grab a couple more manual focus lenses in different fl to tide me over.

I made my mind up with getting a Canon Fd 35 f2.8 to play around with until the e-mount 35mm comes out.

I need help deciding in the 85 and100 range. Would like your opinions on what would be best bang for the buck in IQ. Maybe there isn't a huge difference? Or maybe there is something not listed in the price range ($100-200). Thanks.

Here are the ones I'm looking at. Condition is in "( )"

(100)
Nikon 105 f2.5: $110 (9)
Olympus Zukio 100 f2.8: $124 (8+)

(85)
Olympus 85 f2: $149 (7+)
Canon Fd 85 1.8: $149 (8)
Nikon 85 f2: $200 (Has slight rear element scratch)
