looks like great performance.. how does one buy/use this? every ~6mo i go looking for good eink monitors/devices, but am regularly disappointed

https://www.crowdsupply.com/modos-tech/modos-flow I believe the user modified an existing Modos Display (possibly not the one on pre-order), so I do not know if that developer's mod will go into one of their monitor's firmware. You can ask in their Discord channel (the company is aware of his work)
