Vintage MONO Cartridge Question ?

Grado doesn't do moving coil. They have two elliptical stylus moving iron cartridges, the MC+ with a 3-piece telescoped cantilever for $90 and the ME+ with 4-piece cantilver for $150. The last time I checked, the ME+ was a Stereophile recommended component.

I have an Audio Technica AT-MONO3/LP. It's a high output (1.2mV) moving coil cartridge with conical stylus. It retails at $189 at LpGear.com, but I got mine for around $116 on Amazon. Currently they're $132 there. I'm very happy with it. It's very quiet on old mono LPs and has transparent, honest sound and dynamics. It opened up my 2014 mono Beatles LPs significantly.

Thank you for your response; however it was not what I was looking for. 

Grado offered moving coil cartridges from the mid 1950's-mid 1960's before changing to moving iron.

The 3 cartridges I mentioned are true single coil cartridges, rather than 2 coil construction adapted for mono.  All are vintage, and were made before 1960.  My intended use is to play pre 1962 mono LPs.

I'll never understand why people buy used phono cartridges. <shudder> Yes, you can have them rebuilt, but that's a dicey proposition and you can never be sure what you'll have when the service is complete. If ever there was an audio component to buy new, the phono cartridge is it, imo.
