How to find a roommate in Chicago?

I don't want to go on Craigslist...too many creepers on there. I'm new to the city but don't think I can afford to live on my own. I am very friendly but also very neat and value my private time. I wouldn't want to live with someone who is constantly noisy, messy, and/or disrespectful (i.e. bringing home a different guy every night or blasting their music til 3am) Is there a website/apartment finding service I could go to that would set me up with a good roomie?
