Recommendations for UPS to cover 2 PCs

[Zarathuztra]

Unfortunately my new home has a bit of trouble with power outages.. So I would like to get a UPS to prevent PCs from shutting off when this occurs. I have two PCs I would like to hook up and at least make sure one of my monitors and my router is on the battery backup. So I would hope to have 4 plug connections going to the battery at minimum.

Based on this information, what UPS models are recommended and have worked well for others?

Thanks
