A client asked us what Khan Academy uses to make his videos, and this is answered in his FAQ:

What equipment do you use to make your videos?

I use Camtasia Recorder ($200) + SmoothDraw3(Free) + a Wacom Bamboo Tablet ($80) on a PC. I used to use ScreenVideoRecorder($20) and Microsoft Paint (Free).

Camtasia Studio can be purchased at an educational discount price from Creation Engine.

Bamboo Tablets along with other Wacom tablets are also available from Creation Engine.
