Webcam recommendations?

Never was much of a webcam person, but of course now they’re very helpful. I’d like to get a nice one for hosting classes here, among other things.

A couple weeks ago I borrowed my friends Logitech C920 which had very good results and I was very happy with it. But it’s $100+ and that’s just outta my budget right now.

Does anyone know if an off-brand 1080p webcam that won’t break the bank but will give great results? I see some in the $30 range but don’t know which one to trust.
