EMCO USBHV. Anyone have one?

[eas]

While pursuing the folly of a high-voltage transfer reference for testing a stack of used 5.5 and 6.5 digit DMMs I've acquired, I came across an interesting device called the USBHV from EMCO High Voltage (self-link).  It's a USB powered and controlled high-voltage power source. It looks like it pairs one EMCOs HV modules with a USB DAC/ADC to provide, depending on the model, up to 2000V @ 1W, of positive or negative voltage.

I found one on ebay for $395. That's too rich for my blood, but it does make me curious.  Do any of you have one of these? How's the software? How about programmability?
