Please know that they are the best .. However Bernina is not making  parts or motors for the 800 series 830 and down . The 900,  930 series and 1130 and 1230 .. There are no parts out there or motors. So if it needs a motor  or parts they are used and not Swiss  Bernina made.. Japan is making motors for those Bernina machines. Please educate yourself when buying these items. Any Bernina dealer wil tell you that.
