I’m amazed that Home Depot has become a source for those coils now, that’s good. I always loved the German made Prufrex coils that Jim Judkins used to sell. When he said he wasn’t going to do that anymore, I started buying armature plates on ebay that had those installed, if I could get the complete plate for $40-$60 it was worth it to me. Even though they’re used I had more confidence in those than the cheap overseas ones. I’m down to my last four.
