The modified sine is the output waveform referenced to a pure sine
     wave from the power company.  Modified sines are better for
     interference or sensitive devices.  Frequency controlled will also run
     rotating devices better, closer to rated speed and properties.

According to the latest Camping World catalog, p. 43, in choosing an
inverter, one should:  "Calculate the highest total wattage needed at once
(see chart below) and choose the closest wattage Inverter with a greater
output from chart at left" [of their offerings].  In the small chart at the
bottom of the page, they list typical power usage in watts of many small
appliances or tools [but no fans, nor anything that really seems very
comparable].

One thing i don't understand -- On their list of inverters, the 3 of largest
capacity are marked with asterisks indicating "Modified sine wave and
frequency controlled."  Is this really 'fine print' meaning the true
capacity of the units is less than indicated, or what?
