I don't pick them up because I don't have room to keep them, and to me shipping vacuums seems like a big pain because of the size and weight. Plus I don't usually see anything that rare in my area. Mostly just plastic modern uprights, Elites, or once in a while a Kirby or Rainbow, or Lux.
As far as Broom Vacs, they aren't all that rare. I've seen a few in thrift stores and one even on the side of the road. I've yet to get one though, they seem like neat little machines.
