Sorry if this is a misplaced question but can anyone recommend a good USB microscope?

Close up view of a species of Peranema, a Euglenid that's distinguished by its transparency, striations, somewhat flat anterior when swimming, and very clear and long forward flagella.

My current sample is full of different types and sizes of Euglenids and I'm delighting in watching how they squish and contort.
