Headphoneus Supremus
I'm not exactly sure if this is allowed (and if not, tell me and I'll remove it), but there's a pair of HD650s being sold for $240 over at geekhack.org's classified section (think Head-fi for keyboards). He/She has pictures up and they seem to be in good condition. CONUS only though.

Great price
