Hypercam is my personal favorite, I've never really gotten into Camstudio for some reason.
Hypercam allows you to have a few customizing options.
For one, you can change the stop/start/pause buttons.
You can also MOVE where it records.. WHILE its recording.. If I remember correctly you hold CTRL and move your mouse and it will go with it? It depends on your settings.
I believe in the sounds/audio tab you can enable voice recording.. select the correct options.
However you must buy a microphone, or a webcam with a built in microphone. Some laptops come with built in mic/webcam.. But I'm guessing yours doesn't since you can't hear yourself.
Another cool option in hypercam is choosing whether you want to record your mouse or not.
To me, hypercam wins over the one Orange linked anyday..
