but those "higher grade" versions from Furman and Tripplite are still MOV sacrificial technology.
You can buy Zerosurge for $325 which is more affordable than Surgex, you can also buy used, since serie mode protectors are not sacrificial, they can last many years, there is literally no reason to buy MOV for any components that are valuable, when you can buy a used series mode for $100 these days and chances are it will continue to work flawlessly for another 10 years
I chose Surgex because I wanted those 10 outlets on the same area, whereas other standalones usually only have 8 outlets, with one of those being in the front. Also, the other standalones are only serie mode, whereas the SurgeX is advanced series mode, which is another reason why SurgeX is more expensive.
Zerosurge offers an advanced series mode version by custom order, they don't sell it on their website and I think it costs around $500
The one I posted in the OP used to be $600-650 retail for years
