We bought Olympus microscope, but put a Nikon Camera on top.
We are VERY pleased with what we have.
On the other hand, having had Olympus, Nikon, Leica & Zeiss all giving
in lab demos and leaving the mics. for a few days for us to play with, I
honestly believe we would have been happy with any of them.  I have
no reason to change my mind some 10 months later.
Our mic. is used heavily by PhD students and post-docs.  It has stood
up to abuse!
We paid around £30, 000 (stg)for what we bought - but it is used as a
multipurpose mic.
