in dash multi changer cd

Hi evry one

As you can probably tell im new to this site.
and as most people are, im needing help.
I have a 2004 Bora 130 TDI sport. the in dash cd changer is goosed, and i would like to keep the set up/ dont like changers in the boot/ but dont know where to get a compatible unit at a reasonable price, as the originals seem to be very expensive unless some one knows where there is a used one at the right price, any help or advise will be appriciated..................

Thanks
