One thing to remember about the joule rating is that it?s the surge that the protector will take before it fails. Just to repeat, Samsung doesn't take a position on the ratings but I can give you my personal opinion. A very very conservative rating I would suggest would be 1300 joules. From there, the sky (and likewise the price) is the limit. And if the protector has a warranty, find out what the details are. Quite honestly, I?ve never had an appliance go out due to a spike, so I?ve never had to go redeem one.
That said, I?ll echo that the PowerCenters and UPS? have a reputation for streamlining the voltage. Based on what I heard, the benefit of this is that dirty power isn?t going to interrupt your television viewing (ex - a blender causing static in onle tube TVs).
Sorry to drop legal language again but I have to repeat that Samsung doesn't not have an official position on surge protectors. It's a personal choice. (This is only downside about a forum like this... I can't just speak normally with certain issues. I'm sure you understand).
