I have had my MGS4 80gb ps3 for almost 2 years now and i have had no problems. When i insert a disk the pas3 makes a small noise because it is reading the disc as answered on another forum. However i keep reading online that the ps3 blu ray drive and laser usually fail many people keep saying that sony charges 150 dollars for it to get repaired. I ahve a warranty with bestbuy but i like my 80gb since it has a memory card reader and some backwards compatibility. Anyways should i be worried?
