I have the 2056, which the 2058 replaced. And I have the Grand Quilter. I retired my 24 year old Janome Memory Craft 7000, gave it to my daughter and it's still sewing like a dream.
The one feature that pushed me to buy the 2056 was the IDT feature, now having used it I will never go back to not having it. It's great for accurately piecing as well as quilting. :)
