No clue as to how old. I assume that the 7" is from the right of needle to the "arm" of the machine? I am looking for the largest harp area I can find. I'm not sure I'd use the embroidery component (I am a hand embroiderer) and would probably only use the machine for piecing and fmq. My friend who is selling it, doesn't use the embroidery function. I am soooooo confused! Don't know which way to go - new or "help" out a friend and perhaps not be happy with my purchase. Decisions, decisions.
