There's quite a difference. If you have a 4X on one of your compound microscopes you'll appreciate what you'll be getting from the new one. Also the visual optical path goes through the slide, not the cover slip. But the Trekker has a very good depth of field anyway. What might be interesting is small plastic petri dishes of pond water. Glass dishes have wavy glass bottoms, but the plastic ones are nice and flat and optically quite good. Plastic cells culture flasks are even better -- if you can lay your hands on some.
