The last shopped System One I saw on eBay was listed at $2,200 "The Hulk" but didn't end up selling, also there was a Sinbad in good condition that sold on there last month for around $1,700 if my memory serves me correct (I know Tony would probably remember.)

Actually the last Joker Poker that sold was one in Sydney but it was really on it's last legs and looked like it was dragged out of the Cooks River at the last Clean Up Australia campaign, it went for about $450
