About £15.
Seriously, some frames have the ends of the head tube machined so that the cartridge bearings fit directly into them. The ends of the head tube are usually belled out a bit to allow for the larger bearing. Non integrated have cups that have to be pressed into each end of the head tube. It is these cups that hold the bearings. As far as I can see the only advantages of integrated are:
slightly shorter head tube - useful if you like to get low and aerodynamic
no pressed-in cups to remove when you replace the headset
