A few years ago, I decided I wanted to get a good power strip. At the end of a few hours research, I concluded that there wasn't any trustworthy third party actually doing verification of manufacturer claims, and do not believe that "1750 Joules Surge Protection" actually means anything useful given that I do not trust it.
I just bought a mid-price range one that looked like it wasn't by some fly-by-night company.
It would be really cool to find somebody actually testing these things.
