The best advice I ever received - well at least for computing - is to buy a battery backup for my computer equipment. The tech stated the little power suppressors are "nice" (and he chuckled) but a good battery backup not only protects from power surges but power outages also - a quick drop in power can be just as bad as a big surge and usually damages more equipment than surges since they happen more frequently than people realize.
I live in AZ and we have power surges and power outages all the time and the drops can only last for a blink of an eye which just lets the monitor flicker and lags the game for that split second. I played the other night though a 3-5 minute long drop in power since all my computer stuff is plugged into the batter backup - PC, monitor, cable modem, and router.
Good luck on that lunch break search!
