I own Belkin PureAV PF60 too. Very happy with the looks. It is also good in terms of peace of mind since i know that all my expensive stuff is properly (I hope) protected from surges.

I can tell you guys at least one accasion when my power conditioner helped me: I had a terrible hum at my old place coming from the cablebox, which disappeared once I run the cables through the PF60. Usefull, isn't it!! Yet, I did not notice any improvement video or audio wise.
