I have the Bernina 820 & it scared the heck out of me at first but wouldn't do without it now. Harp space, BSR, huge bobbin. has a feature that counts down the amount of thread left on your bobbin & lets you know when thread is getting low. It is quality from top to bottom but it is NOT a machine to travel to classes as it weighs a ton. One big feature for me is it is not made in China. Be aware of where your machine is made!!! Love my Bernina.
