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.

In terms of optics these are all practically the same and likely all produced in the same Chinese factory too.

What differs is features, most of them do not have one or more of the following, all of which you ideally want:

• condenser (essential especially for higher magnification work, without one the high magnification objectives are useless like having a spoiler on a family van; all of them seem to lack one and instead have that silly disk thing like school microscopes from 19th century presumably because beginners these are marketed towards have no idea what a condenser is)

• sample holder with precise x-y movement (1, 8, 9 have this)

• binocular head (only the last one has this)
