I own Snapz Pro X and have not been happy with it's screen capture capabilities. So I was researching some others including ScreenFlow, Screenium and Jing. Some are relatively expensive, some are reasonably priced but Jing is free.

Well, Jing just blows me away. Not only is it PC and Mac capable, it is so easy to use and quick to learn. For doing quick screencasts to share with others, either as a URL, or to embed in a website or blog post, this is just incredible. Check it out.
