[iBook] CD (only) tray loading drive for ibook 500

Hi does anyone know the drive I should get for my ibook (dual usb)?

The one currently installed may be dead.

I want to get one which would be exactly the same as the factory 
installed one but it doesn't have to be apple branded. What brand/model 
USB did Apple use in the ibook 500 (dual usb)?

Thanks

PS I want these specs as I want to mount the cd plate back on to the 
replacement drive and don't want to tamper with it much.
