I have a brand new kirby model 561 that has only been out of thhe box oncen . Never been used. Not sure what the pricing is ...anyone know ? Please thank-youjr
The best thing I can say is it's worth what someone is willing to pay for it.
I'm guessing if it is in good condition and NIB you might get between $150 and $500 depending how you list it like ebay etc. It would be nice to see pictures of it.
