a vintage Bernina, or a newer Janome, Elna or Kenmore...these 3 are made by the same company now and have many like features and interchangeable parts! Kenmore has been in the top # machines for the last 20 years...
Good luck finding what works for you!
Oh, you can go to allbrands.com and do some serious comparison shopping before heading out to shops..helps to go with some information in your notebook!
