[vet-mm] Screen Capture Software for making Student VodCasts OSX

[Stuart James Bush]

Hi all, (especially those Mac users)

I'm looking at suitable, flexible and affordable screen capture  
software for Mac OSX. Some of my students are behind the 8 ball and  
need to get extra help. I want to do about half a dozen VodCast Tutes  
on certain areas of Web-Design and Animation to help them out. Has  
anyone used anything they have found very useful yet (and  
affordable :)  )

Regards
Stu.
