Torus RM60 BAL vs Richard Gray Powerhouse

If you are getting flickering lights and only 110 volts at times out of your wall outlet, you would be better off with a PS Audio Power Regenerator. It will clean up the line and give you a steady 117 volts.  You may be able to grab last years model for a decent price or find a used one here.

Mzkmxcv: my homeowners insurance covers my electronics, so I'm not really concerned with that end of things.

Stereo5: I've considered the PS Audio products in the past...the PS 5 and PS 10 look promising for a front end application.

It’s not about the fact of if you need the warranty, it’s the fact that the manufacturers stand behind their products and are confident in its performance. Would you buy a car from a new brand that doesn’t have a powertrain warranty?

...  in the summer my 120v is often more like 105-110v with neighborhood demand.

Are you in the US? If so, that voltage is way out of spec in many states, where about 114VAC is the specified minimum. Although electric utilities can be very unresponsive to we audiophiles - I've learned that the hard way - you're best next step is to work with your utility to get your service corrected. It's likely that it's not only your voltage that is bad, but current, too, which can be tested and measured.

mzkmxcv"The fact that I’ve seen even $100,000 warranties for the surge protectors at Wal-Mart and no evident warranties for the two products you mentioned, should should how confident those brands are in their products protecting from dangerous surge"

This is a naive, misinformed, and short sited way to arrive at a consumer purchasing decision if you buy a car that way you will end up with a Hyundai which has a better warrantee than a Mercedes so tell me which you think is the better car many companies issue warantees that last longer than the company will even be in existence!
