I recently purchased Camtasia and SnagIt. The are not only superior products, but are backed up by excellent support and a strong user community.
Today, I added an annual subscription to their ScreenCast service.
I purchased Camtasia and SnagIt bundle through Amazon. It is the same price as purchasing directly from TechSmith, but unfortunately they used Digital River as their payment portal.
This is the only negative thing I can say about TechSmith is that they use DR. See my review of Digital River on SiteJabber for a view on my experience with them.
Fortunately, when my DR purchase was rejected I was able to call TechSmith directly. Their sales department took care of me in a professional and courtesy manner.
