Just got it from Amazon, brand new, then I realized I needed a bigger one for my new apartment. Selling this one at $50 (bought at 64 plus tax from Amazon).

This one is 72'' W x 70.25''H. I can deliver it to you sometime between 3~5pm tomorrow (sunday) if you are within 30 miles to Stanford campus.
