But thanks to my UPS unit I had bought 2.5 years ago (an APC), only the UPS itself got fried.
That unit (the XS900 model) cost me $125 2.5 years ago, and just saved a router, cable modem, 24 port gigabit switch, external HDD, $5k computer system, and two phones from all being fucked.
I just replaced it with the XS1300 model for $160 (I bought them both from Best Buy).
If you are at all serious about your business, I strongly suggest you get one. Remember, data backups are useless if they along with the original both get fried from an electrical surge.
