Yes Suez, the better built surge protectors are.
I would ask Statler what protectors they recommend. Do you have extra insurance for your Statler? If not, I would check into the possibility. I would also check with a local electrician, or several, for their recommendations on what protectors they would use. Check with a local electrical supply house? Also check with the website of any surge protector that is recommended. Do they provide a warranty for items plugged into their equipment during power fluctuations?
This is the reason during storms that many of our quilters are now reverting to the treadle machines. No electric, no problems, they can keep sewing without worry. With that said I do think you're doing right to unplug everything during electrical storms or the threat of storms. Did you know that you can have lightning without clouds when the storm is many many miles away and have damage?
