* Those "couplesurgestrips" did what no protector must do - failed.

I "fail" to see how that is bad - apparently an overvoltage got
through my whole house protector (according to the power company, in
their nice "GFY" form letter, a high voltage line was knocked into a
low voltage one by a falling tree, neatly bypassing the transformer,
so it must have been a big jolt) and the surge strips shut themselves
down rather than pass through the overvoltage to the equipment
connected to them. The more recent surge strips that I've purchased
(I don't ever buy simple power strips; I figure if I need a power
strip I'm probably going to have enough stuff plugged into it that
surge protection might be a good idea, esp. for interconnected
appliances like a rack of stereo equipment, computer peripherals,
etc.) have a warranty where if you keep all your paperwork the mfgr.
will replace the strip if this happens; as it was the ones that failed
were all ancient (one had a date code in the late 90's) and still and
all I'd rather spend $30 or so on a new one rather than have to
replace the equipment connected to it. If I see a storm developing I
do go around and switch off and/or unplug all the surge strips that
aren't powering "mission critical" equipment as well, but in this case
the incident happened at the very beginning of a storm, while I was
away from home, so I didn't have the chance to do that.
