The APC and Tripp Lite surge suppressors and line conditioners are probably as good as any without the high prices and the hype. If you really want to "clean" the power you need to get into something like a power conditioning transformer. They are quite big, heavy and expensive, not the type of thing you will find in a power bar.
Most power bars use MOV's (Metal Oxide Varistors). They simply short small power spikes to ground. They also fail over time and after large spikes. If you are lucky they will short large power spike to ground and save your equipment. As often as not, they will just go up in flames and burn up your equipment. MOVs are worth about $2 each. Surge suppressors typically contain about 3 MOVs. Do not ask me why some companies charge up to $200 for power bars. Maybe it is for the "insurance". :roll: You might get to collect that or there might be a loophole you forgot about. (Better read the fine print again.) APC and Tripp Lite offer a "lifetime warranty". AR says the power bar (and warranty/insurance) is only good until the first spike. Then you must replace the power bar, at $100-$150 a pop.
You can build your own MOV surge suppressor (including flame resistant metal box) for about $10 in parts. There are much better surge suppression devices available. You will not find them in many power bars despite the high prices. If you are lucky they might have a little coil and capacitor inside to filter out some RF. That is another $5 worth of parts. :-?
Monster seems to have gone to great lengths with some of their line conditioners. But wow, US$1300 for a line conditioner?
