Now that VFDs are affordable, there really is no problem, unless you want to put in a whole factory full of Fadals or whatever. Then, they'd MAKE you get 3-phase anyway.
There are places where the power is really bad, like at the far end of a 15-mile rural road, where a bunch of guys have welders, central air conditioning and electric clothes dryers ahead of you on the line. But, in most of the US, single-phase power doesn't mean BAD power. Our power here is amazingly reliable. When I was a kid, every time there was lightning, the power went out. Now, it is a very rare event. I have no UPS's on my computers, and generally go 45 - 120 days between reboots, and it rarely has to do with power problems.
