The only thing stopping me from buying a great pump is how unreliable the power grid is in my area. Lines are above ground, with numerous trees overhanging them so a snow storm is high risk for a power outage at a time I can least afford it, as road conditions may prevent seeking shelter elsewhere. Conversely, with a furnace and a small generator to run the blower, I can keep heat on through a couple days without power.
