Need advice on purchasing an standard everyday microscope for a research lab

Hello everyone,

I am looking to buy a pretty standard binocular compound microscope for the lab. The main use for it is counting cells using a neubauer hemocytometer and take images using a 10x objective, which means I need this microscope connected to a camera and a laptop. I’d like the price to be below $600.

These are some options I’ve found:

If anyone has worked with these microscopes if you could kindly give me some feedback on them or recommendations on other microscopes to look at that would be very helpful.

Thank you,
Yong
