Favourite Eye liners?

My favorite is Covergirl Perfect Point Plus in Black. It comes with a little smudger tool at the end, which I thought was brilliant to smooth out and smudge the eyeliner to make it look more nature. It doesn't require a sharper (another plus) because it is auto-sharpening. I think I paid like 6 dollars, but for the quality, it should be worth way more than that.
