Felt tip eyeliner pens can be such a double-edged sword, but Tokidoki Perfetto Eyeliner ($10) is cute and cheap enough to be worth your while. Since it's a marker, there's no smudging here at all, and you won't get undereye run off. It also comes in several cool, quirky colors, so you don't have to go with basica black, and the pen liners are great for eyeliner beginners. The only caveat here is that felt tip liners dry out very quickly, and rewetting them doesn't always work. So if you're not an every day liner user, you may want to consider the Urban Decay pencils instead.
