My friend's DH bought her the new 830 and she hates it. It is way too much machine for her. She does not use 3/4 the features and already had to have it in the shop four times. One fix was under warranty the others was to remove a bit a thread that was caught in the needle/bobbin area that she nor her DH could get out. The cost of those were over $200 each as the housing had to be taken off. She was told it was user error each time when the thread broke and the end was pulled in the machine. She uses the thread and bobbin the tech says to use and doesn't reset the tension from where he sit it, and only pieces with it so she won't get another $200 bill. I told her I'd tell the tech and owner to stick the whole machine where the sun doesn't shine and find a different dealer to help her with it.
