ZYX cartridge and advice

I have read with great interest the comments on the ZYX FS cartridge. I have a mid-80’s Koetsu Rosewood that has been retiped once by Expert Styles in England. It now needs to be completely rebuilt. I can send it to SE Asia Koetsu and have it rebuild and upgraded to a Signature for $900.00 US or purchased the ZYX FS new for $1100.00 US from Juki in HK. Have you compared the two cartridges or listened to them, and what is your opinion?
Has anyone compaired the low or high output ZYX.

Thank you for your comments.
