I have a 301 and I love sewing on it better then my new machine. It never messes up, it never causes me any frustration at all. The bobbin winds at perfect tension. The stitches are perfect, it's sturdy so it doesn't vibrate or wobble. It has sewn every type thread I have used on it. It takes a special bobbin so don't try to use a regular bobbin. And remember it threads from right to left. I found the light bulbs that fit it at Ace Hardware. If you find them for sale buy several. They are under $2 at hardware stores. They aren't stocked in most stores.
