"New" model VPI?

Right @mofimadness, the biggest difference being that the HW-19’s floating subchassis was isolated from the base and plinth with a 4-spring suspension. Also, the HW-19's top plate was a sheet of aluminum (stainless steel in the Mk.4 iteration) bonded to a 1/2" thick sheet of acrylic.

"Pure Fidelity turntables which I prefer over the VPI I had"

Blisshifi, PF appear to be a notch above VPI in build. Never heard the brand, but all the reviews suggest you get what you pay for.

"It’s a modern day HW-19 with updated technology"

mofimadness, that’s what came to mind.

500 RPM motor- curious what the thinking is here? VPI was stuck on 300 RPM motors. Still no real time speed control like Phoenix  RR(now SOTA)

According to this:

The 500RPM motor is for the 230v countries.

The Stainless Steel/Acrylic top plate was on the MKIII and a few of the first MKIV HW-19's.  I was a VPI dealer and Harry told me that stainless steel became too expensive and they switched to a black metal/acrylic top plate later on in the MKIV version. 

I upgraded a bunch of these tables, way back in the day for people.  I know the HW-19 tables very well  :-)

Belt drive, rim drive, direct drive, mass loaded plinth, spring suspension plinth. standalone motor, onboard motor, 300rpm motor, 600rpm motor, fixed tonearm board, removable tonearm board, four feet, three feet, uni-pivot, gimbal...sounds like VPI has all the basis covered!

Very interesting...."modular" design. I have a Superscoutmaster I’ve tricked out just that very way...... Rim drive, Ceramic platter, dual motors, SDS. 2nd pivot arm....etc. It sounds great The unipivot arm has gotten lots of bad press...... I like it.....the more careful the setup, the greater the rewards.
