I note the forum post date is January 17th, 2011 I purchased my Acorn on 29th April 2013, almost 2.5 Years later.
During which time multiple Acorns and CPU cards came up, and every last one had very aggressive bidding on them,
reaching prices aproaching $160 - $200 !
There is currently only one Acorn PC700 for sale world wide (as far as I can tell) I have checked ebay.com.au/uk etc
so (if I can borrow the commodore example) you could say a commodore has a known market value because there may be 25,000
commodores for sale throughout NZ and you can compare prices, but who can say what the market value of a commodore
is if its the only one in NZ and no other commodores are in car sales yards (they have gone falcon) ?
Its true of every computer sold on TradeMe, someone somewhere has paid a lot less. I dont necessarily think those traders who
pay more have bidding fever, they just really wanted it and took control and won the auction under circumstances where
there where no other place where they could get that item, rather than wait for another to appear somewhere,sometime
