- Lighting and visibility: LED lighting helps with precise stitching and reduces eye strain on long sessions.
- Extras and accessories: Bundles with extension tables, extra feet, and bobbins can add value, especially for quilting or upholstery work.
- Maintenance and support: Check for available manuals, customer support, and ease of finding replacement parts or presser feet.
