I'm working on a Scrappy Jacob's Ladder. Started piecing with my Standard, but switched over to my Two Spools since I like the foot on the Two Spools better than any of my other machines for piecing.
I like the feel of the Standard and Singer VS2, but wish they had the feet of the Two Spools. Two Spools can be a bit louder than the other machines, minus the Davis NVF.
