I have the Pfaff 2044 Quilt Expression, bought it used in 2011. It has been a great machine, user friendly for this sewing newbie. The things I miss is the adjustable foot pressure and the wider, taller throat area. I going to think there is not a lot of difference between the 2044 and 2046. I find my 2044 is sluggish when mitering corners, getting the numerous layers to pass smoothly under the foot is a struggle. I find I to pine for the 6600, the Pfaff 5.0 or the Janome 9400. I love the IDT on the Pfaff and fear it may have me spoiled. The 6600 is closer to my price range and love the user friendliness of the 9400. Decisions, decisions...
