Back in the day it was like 3-5,000 fully installed and warrantied. It might be worth visiting the local bank and seeing if they would loan on such a home improvement. Might be able to get one for little money down, on a fixed payment. I can tell you after almost a decade of owning one, Idk how anyone lives without them in the country lol. Especially if you're in a small town thats last to get their power back.
