My friend has one like you want and loves it. I thought the threading was very cool.
However, I have a Bernina that I bought with my Bernina sewing machine back in 96, I think. I love it for home sewing and I too will serge blocks together if I need a quick tie baby quilt. It is computerized, takes a couple minutes to thread but not a big deal. It broke my heart that I did not have room to bring it with me. But I remembered the old days of the zigzag method of seam finishes and have survived. Even have a foot that does a similiar edge stitch if the fabric does not over ravel??? Enjoy your purchase. I know they are costly; but, I made all my daughters clothes as she was growing up; every curtain, most of my clothes and husbands shirts and ties (before they allowed teachers to wear polo shirts with collars.) I still sing serger praises. Thanks for listening.Teresa
