Logitech HD Pro Webcam C910 and we enjoy it. The picture quality is not equally as good as that of our Nikon video camera, and the photo editing program is not as better as the standalone program we bought -- but that may not be a flaw in the camera or its software. That's comparing it with different kinds of products.
For video recording, it's best. We did this solely with the webcam, edited it and uploaded it to YouTube, and inserted it into our web page. We never had to look at the documentation or help, either -- it absolutely was amazingly painless. It took close to an hour, counting opening the packages, setting up the cameras, choosing a topic for our experimental video clip, filming it, modifying it, and getting it onto the website.
In later uses, we have discovered that some situations require an additional microphone, and we have gone back to iMovie during our editing, but we're using the camera daily for video filming and for video chat.
I can tell with confidence that it is possible to use this camera straight of the box with no additional components, software, or education, and to get good results.
