Neil,
Pointless suggesting C3/SC3..He has already been down that road with a C2 which I think he re-sold as may have been too big for him.
Even if he considers C2/C3, bad idea to consider from the supplier of C0. C2/C3/SC2/SC3s usually packed in plyboard case. If the courier cant handle the C0 cardboard case with polystyrene packing, they will guaranteed not be able to handle the case for the C2/C3/SC2/SC3.
