20 GB also is reduced in price. 60 gb is uncessary mainly because items can be deleted to make space. I often deleted demos, videos, trailers, old arcade games etc to make room. UNLESS you plan to play 30 games at the same time, I would get the 20gb. Besides, anything you purchased on XBL and you deleted from your HDD can be re-downloaded at no cost, so if you want to play that certain arcade game that you paid for but deleted, you can re-download for no extra cost. I have a TON of game saves and still have about 6GB left.
