I just noticed that NOS SAE MC cartridges are now available on eBAY. I purchased one of these probably 10 years ago. They are high output moving coil with I think 2.5mV output and are loaded like a MM cartridge. This is the "E" version (elliptical) - I bought the "LT" version (line tracking) which might also be available. They are selling for cheaper than what I paid.
