About tuppence I hope. They're VERY unreliable, have complex multi-pole switches that give constant trouble and you can't get bits for them as far as I'm aware.....
They're desirable now as ornaments/museum pieces, so I expect they'd go for thousands.....
I liked my 700 ZX/E (next range down frm the 1000. The 700- XZ/E, XZ/L the latter with automatic tuning I think), but the CR7 sounded clearer and had a better frequency response.
Sorry to spoil it mate, but I remember these things......
Tear down these walls; Cut the ties that held me
Crying out at the top of my voice; Tell me now if you can hear me
