I recommend the Furman PST-8 line. Tested by Wirecutter and the let through voltage is low.
I had a different Furman unit a while ago (an M-8, I believe) and it seemed to have protected my equipment while I was away on vacation. Came back to find the 'Extreme Voltage' LED was lit and the unit was off. Once I reset it, all the connected equipment powered on as normal.
