My favorite vacuums bought on ebay
would be my Hoover 29 and my Lux XXX. Both were complete except for optional equipment and owner's manuals, in great condition (other than needing a little polishing), and priced right. I also bought a model 40 Lewyt and an Electrolux G off ebay, and while they were also priced right, the Lewyt was missing wands (but did have a complete attachment set otherwise) and the Lux G had a leaky hose (although original), the wrong rug/floor nozzle (white), and was missing the upholstery/dusting brush and the crevice tool. Otherwise these 2 were also great vacuums, the G probably being the most powerful and yet quietest tank I've got.
