I don't think anybody in the world will pay $2000 for the Kirby. Fully restored versions of your Kirby have been on Ebay for around $700 (without attachments)and they did not sell. I think you should be able to ask $250 for the Kirby with the attachments. The Royal should fetch more than $100 but less than the Kirby. Of course my opinion isn't worth much. You will learn real fast what people are willing to pay on Ebay. Take good photos of the Kirby attachments because they are what will cause people to start bidding on your Kirby vacuum set.
