By all means get a real microscope on ebay. Search under vintage microscopes and used microscopes. You'll see a wide range but look for Bausch and Lomb and Tasco from the 50s and 60s. These will be used high school and college scopes and most were well cared for. I just got a Tasco for $15 that is like new. The difference is astounding compared to using a pocket microscope or loupe.
I mean I can see a whole freakin herd of trichs in one field of view, and you can see clear, cloudy and amber at the same time. Awesome. Even if I paid $100 for mine it was one of the best investments I ever made. Ask the seller specifically if it is working correctly and if it needs anything.
