OK I know that in the future I am really going to regret this but in the interests of simplifying my life/systems I am selling my DH1 cartridge.
Anyone who knows the name of this knows just how good it is and worth all of the £5000 it costs. This one has been used sparingly in first a NWA SME 3012 then a DV 507 II for about 120 to 150 hours.
I would love to get as close to £3000 as I can for this but please make me an offer - you never know.
