Simulating a Whiteboard Doesn't Have to Cost You an Arm and a Leg
... It really doesn't. While there are many hugely robust online services and software that will give you the ability to conduct a "pen-and-paper" type whiteboard presentation online (e.g., WebEx, Eluminate or Blackboard, NotateIt, to speak of a few), the fact is, something as basic as a blank/white image file or (even better) a blank PowerPoint slide, along with screencasting software, like Techsmith's Camtasia, can get you a long way when creating a whiteboard effect for screencasts.
Then, add to that the utility of an input device like a Wacom tablet so you can use natural pen- and pencil-like strokes, then you have the makings of a compelling extemporaneous screencast presentation.
The video above shows some of the tools we could each use. Take a look and let me know some of the other tools you've used before. I'm always on the lookout for new tips and tricks.
