Best screen recorder for Minecraft?

I'd like to find a screen recorder that I don't have to buy and easy to use, Any suggestions?

Try camstudio its free and easy to use - http://camstudio.org/

Try Bandicam that is free but can record only 10 mins.
Then there's Fraps the size videos you record with it are HUGE example 10 mins 20 GB.
So make sure you have space on your computer.
If you want to upload it you need to lower the size. You can do that with a program not sure what its called it can turn a 20GB video into 500MB witout changing the resolution and other things.
