This info I agree with a lot more. I was more taking exception to your first post that seemed to make Northwestern COL ridiculously expensive. I just wanted to share that their are many, many options and those all range in price and have their own plusses and minuses. I do not think the commute for living away from school is bad at all. Express busses are fast up and down Lake Shore Drive and the El is not slow (unless you're talking the Brown/Purple line into the loop, which you wouldn't do to get to school). The worst part of my commute from Wrigleyville is the walk from the Chicago red line stop to school and my commute is at most 30 minutes door to door.
It should be noted that the poster also ignored the existence of the busses. It's the same pass, and express busses are magic. Live on the 146 or 148 and your life is easy and cheap.
