Helmets

Just sliced the top of my head open this weekend from the board coming off on a crash. New bindings, didn't have them cinched down as much as a should have. Still on some crashes the bindings will come off. I'm looking into investing in a helmet. Any reccomendations out there for what brands work good? look cool? priced good? I figure it's worth not having to worry about making another trip to the ER. There are enough other injuries to worry about, so wearing a helmet is starting to make sense.
