Our PS3 stopped readding discs about a week ago, went through the whole software re-installing process with Sony (which took 3.5 hrs) and no luck so it's the drive. Sony want £134 to send you a re-manufatured console.
I'm considering my options but as you can get a new 120gb slim for £200 I don't think I'll be paying sony £134 with a 3 month warranty.
Can you repair these yourself at all? I see you can get a new drive from ebay for about £50.
