Hello Brian,

    I guess one of the main spec you would be concerned about is the
    working distance. I used Nikon SMZ-10 and other newer versions for a
    long time in my ex-job (was a neuroscientist for 13 years) in
    microdissection. After I switched my carrier I bought one of the
    SMZ-series microscope for engraving, but soon realized that its
    working distance was not sufficiently long. So I ended up selling it
    and bought a BM-1 microscope from MEIJI TECHNO. BM-1 allows working
    distance of 170mm at the magnification of x10, and that is sufficient
    for my stuff. The working distance of Nikon SMZ series ranges
    depending on the model, and I cannot remenber off-hand the exact
    value for SMZ-10, but I bet it should be something between 70 mm and
    115mm. I also have to add that my experience in engraving is much
    limited compared to my ex-job, and that I only use the Japanese
    traditional type of engraving tools (Wa-bori) which may require
    longer working space. 

    I can't compare the visibility of both types of microscopes at the
    same magnification of x40 (BM-1 is only for x10), but my gut feeling
    is BM-1 is practically sufficient at least at x10. 

Hope that helps...

Best wishes
Akiko
