@Mike-Amos Place I'm at isn't grounded even though it's a three prong plug. I'm certain. It's not a rental property anymore it's a 100+ year old house.
I think my only option for protection is either a UPS or I found this one outfit that builds non-grounded surge protectors. Called "ZeroSurge." Only problem is their 2-plug version is $263. I called them up today to double check and the man said, yes. No need to be grounded.

You or Rich think a UPS alone would work?
