R1 Concept rotors for KH setup

When I lived in Europe I once asked them to turn my disks , mechanic looked at me like I was insane , maybe it's a north american thing , turning disks . My thinking is if the disks are scored enough to need turning , not worth saving . Turning costs what 10.00 a disk , for another 10.00 I can have new disks that have not been heated and cooled couple thousand times .
To each his own , sorry for thread drift
