Congratulations, I just bought a Janome Horizon also. My son is a computer geek and he bought me a surge protector that cost over $200.00. He said that is the only one that would be safe to protect against different kinds of outages. The cheaper ones can be hit once and they are not good anymore. Sometimes you would not even be aware this happened. They only protect against a surge. If it were up to me I would have just used the cheaper one and not sew when it's lightening and unplug my machine when not in use. We do have a whole house protector put on the main box. I don't know what that does. We have lost appliances in the past with a surge.
