Buying my first microscope!

Hello friends!

I am new to this world.

I have been watching and now I wanna buy my first microscope + camera.

What do I need to get as close as possible to the image quality as on Journey to microcosmos videos?

I know they use stuff to get the background black and also DIC-technology. It’s not needed for me but it would be cool.

Could you guys drops some links or model names to microscopes (camera mount, DSLR-preferably, is required).

I know I wont get the same quality as they do but please link the best cheap ones! maybe 300-600 USD range. Used or new.

Best regards,
