So I've gathered.  Commercial, industrial, and rural farm tend to be the 
places where 3ɸ is a viable option.  Beyond that, ya rotary converter.

The more that I learn about VFDs, the less that I like them.  Especially 
for anything electronic.

I'd much rather spend the additional money and have what you are 
referring to as Hubble spec-grade outlets throughout the house.

I've gotten to the point that I don't want to put up with / tolerate 
sub-par things that are going to cause me to have more work in the future.
