I use Camtasia (http://www.techsmith.com/camtasia.asp http://www.techsmith.com/camtasia.asp). It costs $299. It is hands down the best. It has a technology called SmartFocus which zooms in to where the mouse cursor is. This is very useful with youtube's limited real estate. Definitely put your product demo on youtube. You get exposure from markets that you may be unaware of. You can see where I've used SmartFocus here: http://www.youtube.com/watch?v=cL9qS6bAMPU http://www.youtube.com/watch?v=cL9qS6bAMPU
