If the power center (and these sell for up to $500. retail,
depending on model, features, and where you buy them) really
does what they claim, or at least imply, it should die
immediately in a really bad strike, *without* passing any
current beyond itself.  I'll have to review what was said
in the thread, but I suspect that's a major exaggeration,
OR it would not happen fast enough.  Yes for rolling brownout
surges and spikes, but Not for lightning.  OTOH, these units
do include a hefty amount of "attached equipment insurance."
Probably mainly a marketing ploy to justify their high cost,
and I haven't read the fine print on the guarantee.  (I wonder
how it goes when someone tries to collect, on a legitimate
claim . . . ?)
