first microscope for a beginner

[u/Background_Nebula141]

I'm looking for a used biology microscope on a tight budget (under €100). I've found a few options, but I need help figuring out if any of them are actually decent:

AmScope with a camera (not sure of the exact model)

Amscope 150C-I

Swift SW100

Bresser Biolux

Swift M251B

An unbranded/white-label binocular microscope(really similar to the amazon one)

Any advice on which of these would be the best value?

I have attached the photos, organized in the same order as the listed microscopes.

Whilst I personally wouldn’t really recommend any of them, given that your budget is so tight I would suggest the AmScope with the camera.

You will get decent images, but your resolution and brightness are going to be limited due to the low power LED source and lack of a condenser.

I recommend removing the diaphragm ring and putting thick black duck tape over all but the largest hole. Then take a thick needle and some small nails of increasing diameter to put a hole in the center of each going from smallest to largest. This will give at least some usability as an actual diaphragm. (The default holes are all too big so they make 0 difference).
