I need to get hold of several drive belts - not for a player, they're for a stack-loading CD copier. They're made of plastic, about 2.5mm wide circular cross section and of several different lengths, and seem to have stretched so much they don't work any more. They come in contact with the disc surface so replacements can't be even slightly abrasive.

Can anyone point me at a manufacturer / stockist that might have suitable belts or be able to make them to order, preferably in the UK or offering cheap delivery to the UK? The machine is a Microboards Orbit II disc copier - I can't give the belt sizes without taking it apart to check.
