I suppose it depends on how much you value your quiet, then, and how
much power you need.
I wish we had some quantitative data.

You are correct, sir - I misspoke. I've been shopping for inverters
recently, so I guess I had "modified sine" on my mind.
What I should have said was that the cost difference hinged on pure
sine inverter-type generators v. traditional alternator-type
generators. You are correct in stating that the traditional
alternator-type generators produce a true sine wave, but the waveform
is dependent upon the speed at which the alternator is run, and is
susceptible to hiccups from misfires, etc. So, the inverter style
DOES provide a cleaner waveform in comparison.
BUT, my comment implying that "traditional" generators were not
suitable for reactive loads was NOT correct. That applies to
modified-sine inverters, not traditional generators.
Thank you for pointing out my error! 73,
Ravi

The cost of portable generators hinges almost entirely on two
things: 1) Pure sine wave v. modified sine wave, and 2) attendant
noise. Pure sine wave (typically, inverter-type generators) will
cost more, as will the quieter ones, all else being equal.
I'm curious how you get a non-sine wave out of a generator that
generates AC directly.
