I have a MC6600 that I love; it is a workhorse machine and I love it. FYI... I received an E-mail on January 1 from Janome stating there is a new Janome sewing/quilting machine coming out in April in honor of their 150th anniversary. From what I understand, it is based on the MC6600 but will have an even deeper throat for easier quilting. However, the page link they sent is no longer available and I have seen no more about it.
