What kind of pencil sharpener do you use?

I just received the bulk package of pencils that I ordered today, and have been thinking about getting a electric pencil sharpener. I usually use a cheap little normal one that I have, but with softer pencils, the tips tend to break off and get stuck inside. I also have a utility knife thing that I was using before I got the sharpener but I figure that a electric sharpener would be faster and easier. What do you think is best?
