Camtasia 4 vs Captivate 3 Screen Recorders

[Karen]

I've been reading a lot of reviews on the web comparing older versions of Camtasia and Captivate. (Captivate 3 will be released this month.)
   
  After a quick review of the trial versions of each, I'm initially very impressed with Captivate since I had a workable demo produced in less than an hour. The auto-text captions alone saved me hours of work. 
   
  I need to use a screen recorder to capture information for software demonstrations, tutorials, and web demonstrations. Since I will be creating tutorials of software that is in development, I feel that it will be easier to edit one software modification where a screen changes instead of re-recording an entire procedure and re-annotating it.
   
  I need to make sure I can justify the difference in purchase price ($699 vs $299). I need about 20 man-hours of time savings which I think can easily be attributed to ease of use (fast learning curve) and lack of need for editing.
   
  A lot of the reviews are glowing of Captivate, but just wanted to check with other users who have worked with the most current versions.
