If I were insanely rich, I would consider starting a company to make good quality aftermarket reproduction parts just to drive these guys out of business. Extractor rings damn sure wouldn't "start" at $9.99 unless I really had to charge that to make a small profit!

In case you weren't aware of Wisners Inc.... They make outstanding repro parts for a few firearms. Model 70's just happen to be one of their specialty. Granted not the cheapest, but dam fine quality.
