I'd like to suggest you use one of the sewing machines you have - clean up that treadle!!! and save the $200 to repair you Bernina. Then once it's repaired you can decide if you want to trade it in on a new one or not. As far as what kind you get, it depends on what kind of sewing you do. Do you like embroidery? Since you bought that new foot, you must do "other than quilting." Good luck getting your projects done. 8-)
