Many years ago (Many being 11 years ago before the war), when I bought my computer, I bought a webcam. It cost like $50, but it was practically new tech back then. It had a half a megapixel and the audio was a string attached to a can (not included).
I decided with doing online classes and all, I probably should upgrade.
Oh my god. What a difference. I just got the basic level Logitech Webcam C260. It was on sale at Best Buy for $24 (normally $39).
Just in case you don't believe me about the difference in quality. I didn't change the lighting or anything. I took one picture with each. Please see the below:
