How Much Does It Cost To Rent A Tv?

I will need a TV from late August through October.
I don’t need anything fancy/flat-screen/plasma…just a basic, mid-size TV. It will be used in a dorm room.
Rent-a-center didn’t list ANY prices.
Other rental sites wouldn’t let me choose how long I could rent the TV: they said “78 weeks” or “2 years” and I only need it for 2 months!

Whats The Most Energy Efficient Mid-size Flat Screen Tv I Can Buy?
