I got a Swift SW380T and have been pretty impressed with it

These are some examples of the quality taken with an iPhone: https://imgur.com/a/Fvgfk7J

When I started out I got a lot of good info from the youtube channel Microbehunter

I can recommend the mono 'zoom tube' industrial cameras with live USB output. Very cheap in China, often expensive when resold overseas. I think a 4k one should be $100 or less. Maybe $150 including stand, ring light, etc. USB UVC control.
