I’d say it depends on your needs. Since my home would consume four or five of these in a singe hour, I’d say that they were undesirable to me at any price.
For an application such as my own, a whole-house generator is the preferred solution. It costs as much as three or four of these, but can carry the house for days before requiring refueling.
Some of us use a LOT more than that.
But regardless of the number, when planning for comfort, I plan for peak load. Average doesn’t help me when I need things to work. I opted for whole-house backup and it runs the entire house.
