I'm not purely looking for reflected light though, I want to light the
sample through the objective with a laser (with a camera on the viewing
tube ;).

So the only choices (without major metal shop work) are hacking an
epi-illumination microscope (don't see a lot of them second hand on
ebay) or building something from Thorlabs/Edmund Optics tube system?

You would still have the problem of light reflecting of the first
prism and into your eye. I don't recommend that. I periodically work
for a company, Class One Equipment (www.classoneequipment.com) that
sells used semi-conductor stuff and that included lots and lots of
reflected light microscopes. You can also try the Capovani's
(www.capovani.com).Take my word for it, if the microscope is equipped
with a laser there are numerous protections build into the system.
Firing a laser down a binoc is considered rude.

One way to use a laser is to have it on a 100-100 trinocular. When
it's time to fire the laser you pull the binoc prism out of the way.
These have to have a safety interlock so you can't use the laser when
you are using the binoc.

I would survey the used companies, not just e-bay and to save some
money not just Edmunds. They are both cool but e-bay is to amateur
and Edmunds is way to pricey for this application.

Thanks,
