I have had a 2KW generator for decades but it is currently inop and needs work. Fortunately a few years back Northern Equipment advertised a 4KW unit with 110V and 220V output for something like $225. And they could deliver it to the store and I could go pick it up with no shipping cost. I used it for the first time when our power went down in Hurricane Nicole where wind hit and some awnings took down the power lines. I did not need it for Hurricane Ian, since the power stayed up despite it being a direct hit.
Another purchase you might consider is one I made: a window unit air conditioner, which I can use to make one room comfortable if I am running on generator power. You also should buy a 12V to 125VAC power inverter to enable you to run more items off your car.
Keep an eye out for good deals on generators after the hysteria dies down.
