ABC Vacuum Warehouse via eBay offers the refurbised Dyson DC39 Multi Floor Bagless Canister Vacuum in Purple for $299.99 with free shipping. That's the lowest total price we could find for a refurb by $49, and a price low for a new one by $149. Features include ball maneuvering design, HEPA filter, stair tool, nozzle, and brush tool, triggerhead control on handle, and more.

A 3-year warranty applies, although it's unclear who backs it.
