Best inexpensive way to get from NYC to Cleveland?

I’d love to find a cheap way to get from the New York area to the Cleveland/Elyria area. Amtrak is 81 dollars, 12 hours, and gets in at 3:30AM. An overnight, 8-and-a-half hour Greyhound ride is 91 dollars; I’m not sure how comfortable or safe it is to ride Greyhound overnight.

Any ideas for other ways I can get to Cleveland? For example: cheap/chinatown bus lines, websites that coordinate ride-sharing, becoming a courier, secret ways to get good airfare…

Thanks! :D
