      In reference to how long a microscope might remain in good condition,
      ready for use, and desired by its owner; it seems to me that we are
      luckier than hobby or vocation users of some other technical
      instruments. We don't have something "better" coming out every few
      months to covet or make what we have obsolete (unlike cameras, or
      computers, or cell phones etc -- I don't know about telescopes).

      A good microscope made in the latter part of the last century is about
      as satisfying and useful as a good new one, at least for simple
      observations. A couple of years ago I cleaned and adjusted a colleague's
      black Leitz Dialux that had been in regular academic use since 1970. It
      was still in near-perfect condition, and I am sure with care and minor
      maintenance it will last the owner's lifetime and be passed along to his
      children and grandchildren, and still provide them with fine microscopic
      viewing and easy operation. We laid in a supply of incandescent light
      bulbs, and when those are used up after many years, it could surely be
      converted to whatever lamp is current. With gentle use, most lenses will
      not delaminate, gears will not break, and relatively few surfaces will
      show wear (which is only a badge of honor anyway). And if someday you
      want a different Leitz lens or part, most likely you can find it and
      even afford it.

      Into the foreseeable future, the same will be true for any of the major
      brands that populated our schools and labs in past decades. A very fine
      used microscope can now be had for a tiny fraction of its new price, and
      at less cost than a lower quality new scope that will never be as
      satisfying to use or last as long. Even if an older scope needs to be
      cleaned up and some parts replaced, the huge assortment of major-brand
      used microscope accessories, parts, and pieces appears to only be
      getting greater, cheaper, and more accessible with time (and not just on
      eBay but also from dealers). I foresee no end to this in my lifetime,
      and I plan to be using my scopes another 40 years, at least! But -- I
      have an Olympus BH-2 and a Wild M5, both models high in quality, made in
      large numbers, and then surplussed by many (not all) of their original
      company owners. What might be the long term prospects for smaller volume

      People new to microscopy often don't realize that this situation is
      quite different from many other hobbies that need technical instruments.
      So we will need to repeat the same advice, and what a great time it is
      to start or renew this avocation!

      $70 Leitz stand, At least some one makes makes metal gears for the Nikon
      from the 70's at a fair price that first brought the problem to light in
      a big way. Finding a part for AO Spencer, Zeiss and Leitz is usually
      easy. My experience finding them for Wild, Reichert, Vickers, and
      anything else has been bad and expensive. To be fair no on probably came
      to me until they had found the easy parts themselves.
      > I base my choice and recommendations in scopes from the 70's and older
      on cost, performance and availability of scopes, accessories and parts.
      I also feel that interchangeability of parts and accessories over
      various models and years or production is important. In the USA that
      almost always means Carl Zeiss, Leitz and A O Spencer.
      > I also consider resale value of what I buy. I don't think I will find
      any disagreement that Zeiss has he best resale value of them all. But in
      the USA Zeiss, Leitz and AO Spencer all hold their value better than
      less popular scopes from the 50' through the 70's.
      > The UK has a much wider choice of brands at much lower prices or so I
      am told. Older Lomo's and Zeiss aus Jenna scopes from that time frame
      are almost non existent in the markets I see in the USA.
      > Europe seems to have a much wider range of choices with Reichert,
      Lomo, Zeiss aus Jena and other makers that I know little about.
      > Some Lomo optics are as good as anyone makes. They have some
      objectives that are unique as they are the only ones that make them.
      Their line of water and glycine immersion lenses are 2 among many. Their
      stands aren't up to the same quality and durability of Zeiss & Leitz.
      But no one else made their stands like that either.
      > My favorite scope to use is a Nachet 300 with DIC. I can't find
      anything at all about it. I hope to fit the DIC parts on a Zeiss stand
      so I can have the rotating stage, wave plates, rotating Polarizer and
      Analyzer. Finding those parts for the Nachet is a hopeless quest that
      take the rest of my life and still not be found. All I need to finish
      the conversion to Zeiss is to make a modified condenser carrier to get
      the condenser high enough and make or modify a Pol insert to mount the
      DIC analyzer above the objective.
      > I don't know if its second tier scopes or not. But replacing the
      Nachet objectives with Leitz Pol objectives makes a substantial
      improvement even though the Leitz objectives are made for use with/out
      cover slips and I almost always use coverslips looking at live things
      with the Nachet. Nachet may have better objectives but I have not been
      able to get a bit of documentation on the scope in the 10 or so years I
      have had it. I have not seen another Nachet 300 with DIC any where and I
      haven seen a Nachet 300 in the USA at all. Needless to say I gave next
      to nothing for it and neither I nor the seller knew what it was. I was
      hoping it was regular phase scope. I was pleasantly surprised.

      they are in working condition or you know where to get or make the parts
      you need if its not.

        Look atL
        http://www.couger.com/microscope/links/gcnewbuy.html and

        To see if that suits you. I need to reorganize the mess of web pages I have they are
        scattered over too many place and pages.
