I recently replaced almost every part of my home theater system to accomodate my new HD TV. In the stores I'm seeing these Monster power conditioners that start around $150 and go way up from there. They make it sound like the picture will be horrible (mine isn't) and your equipment is in grave danger without them. Are they really any better than a 1/2 way decent surge protector? So far I only see them from Monster, so part of me wonders if its not a problem they invented.
