PowerSquid outfit their original AC power strip with a surge protector, an audible alarm system, and electronic and radio noise filters. It also has phone and coaxial surge protectors, which I've found a nuisance to hook up, but there's no sense in grounding your power cables only to have lightning jump through your telco lines. It'll easily wrap its tentacles around 6 power blocks, illuminating two of those sockets with blue LEDs when power comes straight for your brand new gaming rig on during a Summer storm.
