To your point of motors, you are never going to be able to get specs
or support on a motor like that, so if you use one, I would not
design like it is going to work across such a wide range. I would
never want to be without very low speeds for things like drilling a
large hole using a hole saw or fly cutter.

TAANSTAFL! At ~$200 vs. $$800+, I realized I must be dreaming. Is
there any middle ground between Baldor and no-name import???
The mill now has a 1HP single-phase motor. I was hoping that using a
2HP motor with a 2HP VFD would compensate for the fall-off in torque
at lower speeds. :-)

I took your advice, and kept looking. It paid off when I found a NOS
Baldor/Reliance 1.5hp motor for a reasonable price (less than twice the cost
of the no-name import). I paired it with an inexpensive sensorless vector
2kW VFD from Amazon, and yesterday, I was able to wire and configure it on
the bench and was rewarded with a (no-load) smooth speed range of 90 to
6000RPM. It'll have a
2:1 reduction belt drive when mounted on the mill.
