OMA or Jean Natais Lenco rebuild

Hi Everyone - I'm looking for feedback regarding OMA and/or Jean Natais Lenco 75 rebuilds. I would love to hear from users or either or both and may have switched from one to the other. Whatever intellegence you can provide regarding sonics, build quality, etc. along with tonearm and cartridge recommendations would be greatly appreciated. I look forward to your timely responses.

Thanks much - Rich
