Create your Own Professional Flash demos with this software $69
Still have this sitting around (so to speak) in the new office. Getting rid of everything I don't need and this copy of Demo-builder is available. Retails for $199 for version 5. Better than Adobe's Captivate in my opinion. This is version 4 with the same basic features (few more bells and whistles thats all).
You can see it at work here. Just did something real quick in few seconds
