I've done thousands of chips using a microscope.  Anything 
down to SOIC size (1.27mm lead pitch) I can do quite nicely 
without aids. But, SSOP and the big flat packs benefit 
greatly from magnification.  A steady table, so the 
microscope doesn't bounce is quite important, too.  I've 
done down to 0.4mm lead pitch on some chips that are beyond 
the capability of our P&P machine by hand with the microscope.
