Good, better, best. VPI Classic 1 accessories and upgrades.

The time has come! Here and now. The venerable Thorens VN-150 (Vinyl nirvana gussied up) Is going to be replaced with a VPI classic 1. Vinyl Nirvana, I like that…
The available accessories and upgrades are being bandied about and I'm interested in which ones you more experienced VPI owners would recommend. The HRX center weight and dustcover are on my must-have list with these others as maybes:
HRX ring peripheral weight
HRX feet
SDS
3D tonearm

Look forward to your input and Enjoy the tunes!
