I'm kind of over-kill on surge/protection since we have so many issues in winter...
- Whole House Surge
- 120v Surge
- 120v AVR
- 120v On-Line Pure Sine Wave UPS
On some equipment I skip the 120v surge since AVR from Tripp-LIte has basic protection too.
One thing I learned the hard way is that not all Tripp-Lite AVR's will "correct" the same % so BE SURE to check into that when comparing, if you go for an AVR.
I don't have the "high end" rack mount, faster switching surge, some day
Also, if you spend the $$ on a nice On-Line Sine Wave UPS you can get them with management/monitoring too! So you can check power usage per-port, reboot, etc...
Check ebay the on-line ups are not cheap but at-least they're 50% off new, I even got a Liebert under support contract.... too bad the batteries were past their coverage when I checked
my buddy did get a weird reply when asking the rep about warranty since the device was registered on the East coast, and we're in CA... lol!!
