Powerbullet (powerbullet.com) allows you to create presentations and save them in .swf format.
Pros: It's free and has a forum with good developer response (and it's Australian
Cons: It can't import and convert Powerpoint files.

Someone needs to get Art a hat for the tip on Wink. This program has the basic functionality of Camtasia Studio (about $300), and creates the smallest Flash files of any of the free stuff I've tried so far. Thanks Art!
