Echlin were exceptional parts but it has changed some since Standard Motor Parts bought them out. If they keep the same quality then they are good to go but it's kind of a mystery now. NAPA still has exclusivity on Echlin as far as I know.
The hand made ones like the Vertex magneto type and the trash can types made for Mallory distributors are the best available but they don't fit all applications. Too many manufacturers don't do good quality control on these products.
