You'll be very lucky. I saw one on ebay once that eventually went for over £500! May have even been £750
I know! I saw it on ebay when it was £100 i said to myself ok, £150 is all i can afford right now, and by the time i got back to the computer to place my bid it went to £225!!!
At the end it went for about £750-ish as you said.
It seems there there would be high demand for them.
