All of my machines are on surge protectors. My Bernina sewing machine and serger are on a Belkin. My Singer 221 is on an APC although it probably does not need a surge protector. My iron is on a Staples. They all seem to do their job. I unplug the Belkin when there are thunderstorms in the area and unplug my Singer machine each time I stop using it; but I never unplug the Staples s surge protector. I'm no help on a recommendation. I'd just get one that can withstand the largest surge of electricity.
