Hi,
I have 6 machines total. Two Bernina sewing machines a 1260 and a 1530 for general sewing and quilting. A Bernina serger with built in rolled hem and a Bernina 650 embroidery machine. I also have a Singer featherweight that I was lucky enough to find at a yard sale for just $20. It was almost never used. I use it for workshops etc. I also have an antique tredle machine I purchased from an antique shop. It still works.
I fell in love with Berninas when I worked for a dealer for about a year. I learned to sew on my mother's Singer featherweight that she purchased in 1936. After she died I let my neices have it as they had learned to sew on it when they visited my mother.
I am guilty of constantly buying presents for my machines like embroidery cards or special feet.
