Better bid me up or I will come on a plane and pay a visit. The manual will be mine I can almost guarantee that. I imagine it will go $20-$40 plus shipping.
If you want it bid on it but i have lost three auctions in 8 months so unless your spending $100 or higher you will lose. Thomas has a 509, 511 and 513 for sale. If I didn't just buy a vacuum I'd buy the 509. Its the closest to an original vacuum I've seen on eBay in some time.
