I bought "The Hot One" (Cadet) from HD for about two hundred. My shop now has three phase, so I didn't need it, until recently. The furnace went out in the single wide and I grabbed it and wired it to the dryer plug for 240VAC. It actually keeps the place as comfortable as the 20kw forced air furnace did, even during the recent zero degree weather. These small units, like the one you showed, are pretty darned impressive beasts. Especially when you consider my fifteen year old can pack two of them without too much effort.
The reason I have what you want is, I never lent it out before.
Scraps are a myth.
