Hi Paul, it has worked really well for me - one nice thing is it supports creating the output in many different formats, like WMV like I used for the tutorial documentation, or also animated GIFs which are kind of handy for small newsgroup posts, and also stuff like Flash , etc... It also has a good built in and easy-to-use editor for trimming out bits and adding in annotations.

But it does cost $300 though which may be a lot if you don't use it much.

There is a free recorder app here: http://camstudio.org/ which is not bad, but not really as easy to use and refined as Camtasia.

Wink (as mentioned before) is also free and I've seen some good results with that as well.
