Oracle Delphi MK1 or VPI Prime????

Greetings!!!

I curently own a Oracle Delphi MK1 with Magnepan Unitrac  ( serviced a year ago with oracle kit), I recently started thinking on sending it to Oracle audio for a new motor and upgrade my tonearm ( I was thinking on SME or Rega tonearm), between those two would cost me around $3,000. I also been looking at VPI Prime, I seen some B stock from 3,500 to 5,500 on vpi website. My question is,

Is really worth it spend 3k on a 40+ year old turntable or should I go with something newer like VPI?

I been recently upgrading my stereo system, couple days ago I turned my turntable, rpm was slightly off, I know paps motor are notorious for going bad. I adjusted the RPM and now its fine. but who knows for how long my motor will work.

Any information/advice that you could provide I will apreciate!

Happy Holidays!
