I'm still new and learning HT, as power conditioners are concern, purchasing one can get pretty expensive, say the APC H15, what happens after 5 years when the warranty is up? Is all your connected equipment still covered after that? I think not, but someone can chime if I'm wrong, another one, the Panamax, which offers only 3 year warranty on there units ONLY if you bought from a Authorized Panamax Internet Dealer List. Monster carries a 5 year warranty. Be careful when choosing power conditioners and look at the warranty. The PureAV, is one of the few that I found left that offer lifetime warranty with connected equipment warranty on there power conditioners and surge protectors.
