I have had machines Diamond for about 10 years and never had it serviced been good to me, the other machines I have all viking are less then 5 years old, I did have to get Opal 690Q fix due to my own fault with the walking foot not on the shank correctly. I do agree with others that moving forward with this trade war stuff parts for many things will take longer as technicians do not keep stock. The technician may be planting a seed, but if your thinking about moving up your machine do your homework to get a good deal, I would not trade in my work horse machine.
