SME Model 15 MK2 vs Feickert Blackbird or Firebird or Sota Millennia Eclipse

Considering possible turntable upgrades.  I have an SME IV.VI arm from about 10-15 years ago and an older Sota Star Sapphire table with vacuum hold down. 

Option 1 - SME Modem 15 MK 2 with new motor

Option 2 - Feickert Blackbird or Firebird

Option 3 - Upgrade my Sota to a new Millennia Eclipse

Thank you!
