I use Snapz Pro almost every day to make static screenshots for TUAW and for print publications, and to make movies of my screen for video podcasts. I love, love, love this program. Sure you can use the built-in screenshot capability in OS X, but Snapz Pro offers much more control over static screenshots and the added bonus of recording movement on your screen. Snapz Pro X 2.0.3 is a free upgrade for registered users of Snapz Pro X 2.0.x. New users pay $29 for the static version and $69 for the movie version.
