I have the Viking 870 quilt. The 870 is a little picky, mine at least doesn't like to travel. I took her on a retreat a few weeks ago, and she didn't do well. I think she got car sick. I think Husqvarna worked out the kinks and made the 875 to replace mine. When mine doesn't travel, she sews like a dream. I love all of her functions and use her almost every day.
