if you use the akaimpc 1000 or 2500 and would like bigger storage, this bit of equipment is a MUST (the akai 1000 and 2500 allows for extra storage but does not come with this hardware and that is a bit of a blow)!!! forget all those compact flash cards... makes loading time MUCH FASTER!!! also... i've seen this bit of kit advertised well in excess of 45 quid WITHOUT delivery so at 26 quid purchased and delivered you really cant go wrong with these guys! nice one dolphin music!!!
