Good Evening TMToronto,
Sorry for the delay, I’ve been working around the clock, and traveling for work, and just able to decompress and reply.
So I ordered the HFS-6515-24-ER11 spindle, a plug and play cabinet, with comes wired and programmed VFD, input filter, braking resistor, main power switch, circuit logic for emergency-stop and reset button, and wired so meticulously, I ordered the Pro Series spindle which is overkill, but I plan on working in aluminum and thinking of a tool changer down the road.
I opted to use an old TIG cooler rather than the unit they quoted me.
The price was about $1300, you could save some money and source the VFD , and build your own box and source your own components, but the build quality, and time saved with plug and play, is worth it for myself with my schedule and needs.
Some saving could be had with the standard series spindle, they do also make a 80mm spindle in air and liquid cooled, just like the 65mm. The quote will vary by exchange rates and what country shipped to.
