I don't know about other parts of the country, but in New York they are RARE. People would suck up a piece of gravel or a penny, break the fan and out to the curb they went. Later 12 amp Elites are still fairly common, but the early Elites (pre-Elite II), not at all. And I can't even remember the last time I saw a Legacy. I will see an Elite 200 once in a awhile, but the better models (i.e. 350/400/600) almost never. They're not as flimsy as Dirt Devils or Regina Housekeepers, but people used and abused them. And yes, the Innovation is probably the rarest modern Hoover.
