Over at Digital Inspiration, Amit Agarwal points out a great deal on the popular Windows screenshot tool SnagIt. TechSmith is currently offering version 7.2 for free download as a promotional deal intended to attract users to the latest version (which is 8.2 as of this post).
So if you don’t need all the bells & whistles the later versions include and are just looking for a screenshot workhorse to take you beyond ALT+PRINT (and don’t already own a copy of HyperSnap or a similar tool), follow Amit’s instructions for a free SnagIt license.
If you’re interested in screencasting tools for full motion recording, there’s a similar deal on Camtasia Studio.
For Mac OS X, check out Snapz Pro X, which does both still images and full motion capture.
