You cannot as easily put the accufocus unit on a Crayford (it uses the pinion shaft cover screws to attach to the focuser which are absent on a crayford). The 10:1 Crayford is good because it uses no power, can handle a lot more weight and has zero image shift, but the 'hands off' motorised focuser can be better if you have a bit of a wobbly mount.
