It's true that Panamax sell those cheap power strips, which are unable to regenerate AC power, filtration of power, isolation of components, balancing power, etc.
However Panamax does build some excellent AC Regenerators. I personally use the 5510 ACRegenerator, and it works fine in protecting my equipment and noise filtration. www.panamax.com/products.cfm?group=1&sec=detail&id=260&ly=h
I also use Panamax UPS 1500 for protecting the lamp in my projector from power outages, so it can complete the cooling process when there is a power failure. www.panamax.com/products.cfm?group=1&sec=detail&id=259&ly=h
