Most of the ones available around here brag about the level of joule protection though the one you linked to from Masterplug is only rated to 370 compared to 1000 or more on most of the ones I've seen. Apparently it's hard to judge the efficacy of that rating outside the lab though.
Our Panamax still shows green lights for surge protection and grounding so I guess it's ok?
The suppressed ones I've been using for the past couple of decades are Masterplug
Belkin should be OK too
