Advice on a bag for 13" WhiteBook

[StevnJ9971]

Hey everyone!
Now that I'm heading off to college, I've been looking for a good bag (preferably messenger-style or similar) that can hold a 13" white MacBook and a book/binder or two. Some outside pockets for holding pens, etc. would be nice too.

Any suggestions?
