only suggestion would be to look at a digital microscope Bob. Bought a cheapy from Jaycar for a grandson and he loved it - easy to use, quite a wide range of magnification and reasonable quality images were available for projects. Then when he got sick of it and put it in the junk drawer, it was no great loss. Should be able to get something of moderately good quality for your $200 - haven't used either, but Jaycar has a better quality one
