I don't suppose it will be a big seller but if you have the Hitachi CG24EKD (SL) and want the trimmer attachment or a spare this is a super deal!
CG-GT Smart fit brushcutter grass trimmer attachment
Suitable for use with the Hitachi CG24EKD(SL).
Amazon have been cut pricing the Hitachi power tools ad hoc for some time, and I'm sure the motor will crashing in price some time soon, so you could speculate and buy the attachment now and wait. Also noted that the edge trimmer attachment is down from £121 t0 £34 another great deal.
