I have been doing FMQ for about a year and have tried it on my Pfaff Quilt Expressions 4.0, my Brother CS6000i and my Elna 6005 Heirloom Edition. I love my Elna, it is a dream machine to me even though it is over 10 years old. I love it so much that I bought a second one as a back up on E-Bay. The Elna is now made by Janome and the feet are interchangeable. I highly recommend this work horse.
