Generic feet won't fit a Bernina unless they have the special adapter and probably won't really fit well. I bought an Aiphasew walking foot for my 830 Record as it was only $50 as the Bernina one was $129 here in Canada. The Alphsew knock off broke after about a year's use. You may be able to pick up used feet on Craig's List (Kijiji here in Canada) or from someone who wants to sell in your area. I bought extra feet from a lady who had inherited a box of feet but had no machine. She was very happy to get my $20 and I didn't tell her how much the Bernina dealer sell those feet for.
