I will be attending Rutgers-Newark as well. Not in NJ right now, but am looking. So far, the nicest place I have seen was Montclair. I am thinking about living in that area... possible Berkeley Heights, but have not visited there yet.
As far as commuting goes, I understand that the train system is a pretty good one. Perhaps it's worth it to look into that before finding an apartment.
Good luck everyone! I'm definately very excited
