fwiw, i've never experienced a detrimental power surge in my decades of a/v experience. i have experienced lots of voltage drops (brown-outs) and black-outs.

my homeowner's insurance (Chubb) covers damage to electronics that stems from power surges like lightning strikes. so that's my protection plan (which I hopefully will never have to use). you might check your insurance to see if they cover this. the price is right - you're already paying for it :-).

i run ac regenerators to deal with brown-outs.

of course ymmv - maybe your building has some problematic setup re: lightning or other things that can cause spikes.

fwiw,
doody.
