Find an even-cambered road, drive at about 25mph, take your hands off the wheel and accelerate gently. Does your car drive straight and true wih the steering wheel in the centre position, or does the car pull to the left or right? Then come off the accelerator and let the car coast - again does the car pull to the left or right? If the car continues straight and true, then in all likely hood you won't need a KDS. Remember the steering wheel must be in the dead centre position - if you need to hold it centre to keep the car going straight, then your alignment is out.
Also, do you feel a significant vibration through the steering wheel at speeds say at 60mph and above? If there's no vibration then the geometry should be fine. If there is then there's probably a slight excess of toe-in, or the camber is slightly out.
