Webcam reviews?

[RMSe17]

I am looking for webcam reviews and have a hard time finding something. Based on stats, it looks like Microsoft Q2F-00001 LifeCam or Logitech C910 are the two top candidates. But I can't find review that compares image quality, compression quality, focus, sound, etc... Anyone know of a good place?

Thanks,
