Best way to advertise for a roommate?

[packerfan]

If you can't find somebody that you already know and trust, don't look for a roommate--even if it means living in a crappier apartment. I've heard too many bad things that can happen. Little things like eating all your food or drinking all your booze while you're gone to big things such as not paying their share of the rent, moving out with no notice, leaving you stuck with the bill. I'm sure there are good roommates out there, but personally, I don't think it's worth the risk.
