Making Homemade Butter

I must admit, I absolutely love this video on making butter. She answers all the questions I have had and it isn't hard to follow. I can't wait to make butter from some of the milk I get from my friends dairy cow. I am thinking about trying some herb butters and freezing those for special occasions. Have you made butter before? And if so, do you enjoy making it or would you rather just buy it from the market?
