I have a couple of decent microphones, a mixer and mic stands, which were bought second-hand primarily for karaoke at parties. I've got all the input gear, another friend has a big PA setup, good fun. Most of the time, those mics and the mixer just live in a bag in my closet, so I thought "why not use them?" The sound quality from an AKG D5 (a decent, but not fancy mic) through a small mixer with a bit of compression applied is just miles ahead of anything you could get from a headset or a webcam mic. It is a little hard to avoid getting the mic in the picture, but with a bit of creativity, it works well enough when placed just above the top of the frame.
