Well it is not too hard to do.
Also, it can be very dependant on the quality of the service.
My local guys are barely able to screw the cart on the arm.. So I am not ready to PAY them to do not better than i can do.
But if you have a real expert, who can dial in the cart after making the technical adjustments.. Then treasure him!!
Most GOOD TT guys have vanished from sight. So having one around I would use his services..
