Consider getting a UPS from from APC (American Power Supply). I live in an area like that too, but the UPS's send steady clean power to your PC for up to 45 min, with never a glitch, day or night. Worst case scenerio- if power is off longer than the back-up UPS back-up battery can handle, then it will automatically shut-down or suspend, or hibernate your system, without loosing anything. I have used them for years and never lost anything. An excellent investment and much better than just a surge protector!
