My Elna 720 has a dual feed foot system, and it works great. You do have to attach the foot and lower the walking part down before using. It is large so I don't use it for piecing. Changing the feet on the Elna is not always ergonomic, and if you want to add the guide to the dual feed foot, you need to screw it in rather than just slide it in as with my old Viking. There's just a lot of fiddling necessary to start quilting. The Pfaff sounds a bit easier.
