Hi Balthazar,
 I find it usually useful to search in ebay for "Completed listings only"
 - though it is not necessarily the real measure.
 I paid for mine 590 Euros plus shipping in 2004. It was a "buy it now"
 price. Before I did not win several normal auctions, which ended in a
 lower price - but it doesn't help if always there is someone bidding one
 euro higher a second later. Finally I do not regret to have paid that
 price. The MonoPoly is my main synth for arpeggios (though my
 Supermax-DX7 is a tough competitor).
