Dammit another reason to hate Apple
Ask around and see if anyone has one lying around or try a computer repair shop I would expect them to charge pennies if anything at all.
Have a wee hunt around there are loads of things to take apart and see if you can find a matching screw (video machines, tape recorders etc) make sure they are broken first though.
you will be surprised what you will find
I just realised I am showing my age there what the heck is a tape recorder lol
Updated for current times (CD players, DVD players) although they are becoming extinct too I suppose
