I've got a very nice Nagoaka MP-50 I am selling to fund the purchase of a Shelter 90x. I purchased this cartridge on March 18, 2010 from its original owner. The body had plenty of hours on it, BUT he just dropped in a brand new stylus.
For all intents and purposes it's new--I hate guessing hours but I would say it has maybe fifty.
I was going to keep this as a standby to my 103D, but I've got bills to pay.
Asking $325 shipped
Note: I don't have the box, but can ship safely mounted in another cartridge box.
