You can get these in bulk on needlecoop on Yahoo. I can't post Yahoo links here so you will have to search the Yahoo groups. They will be having a buy in January I think. They end up being about 6-7 cents a piece. They order all kinds and I use topstitch needles for everything except my mid-arm. I have a Pfaff 7570 and Brother 2002 that I use these needle in without problems. I have also bought from this coop and have not had any problems.
