I have just bought a Bosch GBH 2-24 DFR 110v drill. it comes with a
quick release chuck system to change between sds and normal chucks.
However the important sds chuck bit is missing. I think the part
number is 2-608-572-112 . I have searched for this spare part but can
only find it on fleabay for £25 including delivery.

Is this price ok, or does anyone know of a cheaper source for spares.

Many thanks.
