I'm not looking to keep my computer on, but to isolate it from my house's power surges.

I have Cyberpower 1000va with AVR (automatic voltage regulation without battery) similar to Mike Hanely's. Have used it for years. Gives my system up to an hour of runtime, but more important it protects the system from minor power surges and outages without blinking an eye (although my over head room light will blink). My system is desktop, monitor, router, printer, speaker system, laptop (doesn't really care as it had it's own battery) and powered network switch. Cyber power software uses serial port to give one a real time picture of status of battery, outages, etc. Estimated runtime on battery is about an hour.

I've got my 1000W PC on an APC BackUPS 1375 and it's humming along nicely. I can't recall ever having an APC unit fail on me, though I have worn out and replaced quite a lot of batteries over the years. I'm not sure about other brands, but replacement batteries for all my APCs are readily available at local stores. They have become a bit sneaky, though, as they no longer mark the batteries with the standard markings to encourage users to buy replacements from them. Happily, it's easy to measure the battery and match it to an equivalent in the store.
On a different track, if your service entrance has room for it, they make whole house surge arrestors that plug into a 2-wide breaker slot ( to cover both legs of the 240V circuit). At around $100, they're quite affordable.

For my office and all my home electronics, I use APC UPSs. I've had bad experences with some of the cheaper brands. Change the battery every three years (or so) and you're safe.
For my servers, I use the online models.
At my office desk, I have a 1500 protecting 3PCs, 6Monitors, Stereo Amp.
We have some UPSs that are over 20 years old still in operation, just change the battery every three years.
Walmart Online was the cheapest delivered cost for the last batch of high end APC UPSs that I bought.

I was thinking of going with an Eaton, since APC has had mixed reviews lately. I don't think Eaton is a bottomfeeder company. They seem to make good UPSs from what I can tell.

Eaton is a good company.
I have no skin in the game. I don't trust the amazon reviews anymore.
A key point about choosing the UPS is the size of the battery and how many Joules of surge protection. The software and connection (cable) to shutdown your PC should be included. That is assuming that you leave your PC powered up and unattended.
I have about 30 UPSs from very old 230va to new Online 2200s. All my remote staff have their PCs, monitors, routers plugged into UPSs. I count on the surge protection of a quality UPS as well as the backup power.
One last thought thought that is sometimes left fuzzy. Unless you get into the realm of extended runtime (very-expensive), the point of the UPS is to have enough time to cleanly shutdown the attached electronics.

The main reason I want one is I don't trust surge suppressors by themselves. I have a journaling filesystem and I am judicious about source control so I'm not that concerned about shutting down my computer properly.
Recently nearby construction broke the cable vault and shorted the line to my house, so it wasn't even a blackout but massive sustained flickering all through the house. My computer clicked off a half dozen times before I got to it.
I don't want that happening again.
The construction is ongoing

You bring up a point that thanks to advertising and horrible descriptions on eCommerce leaves people confused.
Surge protection is only for very short power spikes. It does nothing for power drop outs. It also doesn't help for lightning hits - except for extremely well engineered high end systems. Not $6 power strips.
A good test for any UPS, is to unplug it with everything plugged into it and powered on. ** Disclaimer - Make sure you have backups and prepared for the worse case! **
Test it like you are going to use it. Some people may disagree with this statement.

That might be a showstopper for you, but I'm gonna make the suggestion anyway.
Keep the UPS you want to give away as "useless" for you, and use it to power up only your monitor(s) and network gear. Get "something else" dedicated solely for your power-hungry machine.
Monitors/network gear use comparatively little power, but it adds up. If you split the load for those vs your main PC between 2 UPS units, you'll probably be able to keep your PC running for a few more minutes, which can be vital. In comparison, my "older" UPS can keep my 3 monitors, modem and router going for 50+ minutes.
Once your main UPS gets too old to keep your main system going for very long, it can take over the second UPS's job (and then you can retire that one). That way you only have to replace one UPS at a time.

From other comments, it sounds like you want more of an electrical isolation/surge protection.
The ultimate system will include a motor, a large flywheel, and a generator.
