According to TextileArtist.org, the best brand of sewing machine to buy secondhand, especially for fancy work, is Bernina. Bernina, a Swiss brand, makes some of the most highly recommended and reliable sewing machines in the world. New models cannot be bought online, making used models even more desirable.
TextileArtist.org also rates Husqvarna, Brother, Pfaff and Janome machines highly in terms of quality, noting that they are built and engineered to last. Purchasers who need a good, reliable machine should not compromise on their brand choice. Purchasing an older model from a reputable manufacturer is preferable to buying a newer model from a cheaper and less reliable manufacturer.
