Most recent listing that sold on Ebay was on January 5, 2016 which sold for $705. The listing said it included accessories bundle (not sure what that means).
Two current Ebay listings, one listed at $255 and one listed at $1,000.
List it on Craigslist/Kijiji and if it doesn't sell for your price, drop the price by $50 and see if that works.
Just sold my Pfaff Expression 2.0. Originally listed at $750, dropped to $700 after a month and ended up selling for $650 this past weekend (those are Canadian dollars).
