Help needed on buying a microscope

[jaketodd]

I'm not so much interested in how they work, but to buy a ~$200 one with built in video camera that I could save video files of sperm cells moving around. I've heard that needs 400x optical magnification. How about this one? https://amscope.com/products/m158c-e

Thanks!
