Personaly I don't care who owned the Amiga before me as long as it's in good shape and work.
I would surtantly not pay 300$ for an Amiga story ala "The person who owned this machine before me was..." just to see all my friend either yawn or look stupid at me while they ask if I want to buy their spair wornout carweels for only 200$ a pease as they have a history of breaking 160Mph speeding from the cops once.
This crapp belong in a dumpster or at the very best in parts on a shelf somewhere.
