Looking back at this, and the related thread on purchase of the microscope
itself, I want to strongly recommend that you look at the Edmund Scientific
catalog for microscopes as well as slides/slide sets.  I saw some microscopes in
there that will most certainly meet all of your needs, will cost you less than
$500 and carry a 5 year warranty as well.  I haven't seen their guide to
purchasing microscopes but it might be a good idea to get a copy of that before
making any decisions.  Overall, your description of possible uses does not
indicate to me a need for a research-grade microscope, costing $1,000 or more.

Note that I am not affiliated with Edmund Scientific in any way, it just appears
to me that they have stuff that will meet your need admirably.
