I lost my old Fitbit One while going through Heathrow airport last month (got left in a tray when going through the xray machine) and Heathrow's lost and found office say they don't have it. So I'm on the hunt for a new one. Apparently they're not made any more and the couple of new ones on Amazon are going for $290+ (I think I paid about $150 for it new) so my best bet it to find a secondhand one. I don't like the wrist watch models.
TradeMe don't have any listed. Does anyone have any suggestions on other places I could look?
