So I have a Logitech C910 which has since been succeeded by the C920. I didn't pay anywhere near the list price for it though because I got it on a Black Friday sale a few years back. I invested a bit more in my camera because back then it was my primary point of contact for my girlfriend and some friends who live around the country.

That being said, I'm a big fan of the Logitech brand and the C910 was my second Logitech camera. In terms of budget webcams, I have heard good things about the C310: Here Oddly enough it looks like it might actually be the deal of the day for about $15 off of what Amazon usually sells it for (you can see that info here: Price Tracker)

The Microsoft Lifecams Here are nice too, but a bit more expensive and I've had a little more trouble with those. My girlfriend has a Lifecam and the picture quality is great, but for whatever reason her computer has trouble detecting it. In order to make it work she has to unplug and replug the camera each time she boots her PC. I'm not saying that's common, just an issue I've personally been involved with.
