Any recommendations regarding Shock/surge suppressors, high-side only? It's been recommended that we get one. Protecting against the high side is more important for now than the low side. For those that don't know (and I barely know), the low side versions cause the 110 voltage to cutout when it goes down to a certain level. This apparenly protects and circuitry that doesn't handle low-voltage very well. The story goes that this happens more in Mexico than it does in Canada and the US. The high-voltage type is the usual voltage protection. There, that's all I know. Now we need some real life experienced folks to add to this.
