Just wondering if anyone else that uses cord knows of a cheap yet decent cord from home depot or lowes? Ive been using the Zoomed cord but had a friend suggest de-icing cable. After doing some looking I've found cable that would work when plugged in to my thermostat but its around $100 more per 50' cable. Anyone ever hear of this or know if there is an alternative, or for that matter if the price difference is worth it? The ones from Home Depot seem more durable than the Zoomed ones when you look at them.
