No matter what you will get the V4 head and camera... There would be no reason to sell the old head since JD is going to ship with version 4 of the EZB controller... Everything about JD, Roli and Six will be version 4, even the camera as well... Maybe you could retro-fit the EZb3 and old camera into an empty shell of JD, but that means buying just the ez bits and servos and putting in your ezb3 hardware yourself....

i dont have a v3.i ordered the v4 and i like that one cause the new camera is connected straight to the v4 . i do have the old camera.am just starting whit ez so i need lot off things.for now i have the v4 some servo 2 off each servo. some cables the radar sensor,batterie and case,the ttl bt chip.mp3 trigger.am looking for a secondhanded win7 ultimate too, here in belgium.
