monoprice? You don't need a special HDMI cable for your PS3, any HDMI cable will work. As I said, your cable or satellite provider should be able to provide you one for free, just tell them you want it to connect your satellite or cable box to your television, and they will almost certainly hand you a brand new cable in a plastic bag for free.
monoprice does have HDMI cables, and a wide variety as well.
