I probably am not the right person to answer your question. I have three Grace frames but they are all for hand quilting. I also own two Bernina sewing machines that have the needle down feature. I couldn't imagine sewing without the needle down feature. I only machine quilt children's quilts for Linus and nothing bigger than crib size. I don't use a frame for that. In your picture you show two lovely children. Hand quilting would enable you to talk with them while you quilted and be a part of a family group watching TV or just hanging out. You wouldn't have to worry about the children getting hurt while grabbing at the machine and it is totally quiet so you could carry on a conversation. Just my two cents.
