Yes I do. It's well worth the small investment.

I have a 2 phase approach going on. I have surge protectors at my outlets and a power conditioner plugged into them. My machine is plugged into the power conditioner. My nephew builds motherboards and explained it to me.
Surge protectors will protect from an outside surge coming into your home, power outage, brown outs, but most likely not a direct lightening strike.

Power conditioners will protect your electronics from surges inside your home. Refrigerator turning on, deep freeze coming on, air conditioning units powering up, furnace blower turning on, sump pumps starting, Your electric oven element keeping the temperature steady while baking. Anything that pulls a large load of power to start causes a fluctuation in the power going to your electronics. The power conditioner levels it out so the flow is always steady. He recommends Furman power conditioners. The model I have has the PST 2+6.

Hah, I was just going to talk about power conditioners. :)

My DH makes electronic music, so he has a lot of electronic hardware in his home studio, and he uses UPS's, surge protectors, and power conditioners to keep everything safe.

I don't have one in my sewing studio, but I really should. When I'm heating up my iron and sewing at the same time, my machine slows and when the iron element kicks on. I don't think that's good for either appliance.

I have mine plugged into a power strip that has a fuse.

Yikes I never thought of plugging my machine to surge protector.....guess I better get out and purchase a good one

I use surge protectors on all my machines and my iron. I still unplug the machines when I'm done with them. The iron I leave plugged into the surge protector. I mounted my surge protectors on the wall so that it's easy to plug and unplug them. I'm not trusting a surge protector with my expensive machines when they can easily be unplugged when I'm finished with them.

Yep. You never know. There was a surge and 2 of the sockets on my surge protector with the PC and modem were fried. The modem and PC were fine just had to replace the surge protector.
