Now going sideways from main discussion slightly;

whatever generator you go with, you might want to look at a UPS for critical needs- if you get one that has automatic voltage regulation it will deal with power spikes, brownouts, dirty power (like say, from a cheaper generator) etc.

that way when your power goes out, your important stuff doesn't.

Also, if you decide not to go with automatic backup, you get some time to get everything fired up.

One way or another, let us know how it works out
