In response to this request, I went out and bought a webcam for my desktop. I wasn't sure which one would work, so I took a shot in the dark and bought an A4Tech PK-635K from my friend's computer shop. Not as cheap as I would have gotten it from CDR-King, but pretty cheap considering the brand.
The package set Driver-Free. I asked the salesgirl about this, and she said, "Yes, it comes with a free driver." Just had to roll my eyes up at that one.
In any case, the webcam works as advertised, both for photos and videos. Here's a demo of the video capabilities under Cheese.

As promised, no driver needed! Plugged it in and it worked immediately.
It's supposed to have a built-in microphone but it was crappy so I had to resurrect an old PC microphone (the only remnant of an Aptiva I bought over ten years ago).
For my sound settings, it worked with HDA Intel (ALSA Mixer). It helped that I added the Mic Boost option in the panel.
On Skype, I'm just using
pulsefor both input and output.
