I had a Kenquilt, went to the factory in Wichita, Kansas and tried them out and bought it. They delivered it and set it up. Had it about 7 years and had to sell it because of my arthritis. Didn't have many problems. One time I messed up the tension really bad and broke, called them, made and appointment took it to them and they fixed while I waited. For other regular maintenance my regular sewing machine repairman worked on it, he comes to the home, that is really nice. I've been using him for about 20 years and only one time did he have to take my sewing machine back to his shop to fix it, all the other times he fixed while he was here, 30 minutes usually. Not expensive either.
