Usually you do not want the hertz to fluctuate much off of 60 one way or the other.  Does anyone have experience with this area and what type of portable generator is reliable over another?  Thx.

I think you may be looking at this in reverse. You should look for a Line Interactive UPS with built in line conditioning known as AVR (Automatic Voltage Regulation) This keeps the signal clean as even regular utility power has surges and brownouts on regular bases, let alone a generator which can have the same when loads are changing as equipment attached to it changes demand for power.
