cheap hotels in/near Atlantic City?

[chillrob]

Anyone know what cheap hotels there are in or within say 20 miles of Atlantic City. I'm talking really cheap - hopefully no more than $50 for a Saturday night. I don't care if it's a fleabag in a crappy area, as long as it has a good lock on the door and I can walk from my car to the door fairly safely. I have looked online and can't find anything less than about $90 per night, but I am guessing the cheapest places can't be found online.
