Yep, these are great. I have a cheaper "sportsman" 1k watt inverter that has plenty to power my PC and monitor (via my sine wave ups) and also speakers and a fan. It starts easily, runs quietly and reliably so far, and sips gas.
I have a larger generator that I use much less. It's harder to start, noisy, and uses gas fast. Also it doesn't have an inverter so my UPS won't charge off of it.
For most short outages just getting those few things working with a small inverter generator is plenty.
