Been there had that.
I have a high end machine that unless the stars are aligned can give me trouble. But my little 4030 Janome purrs along and never let's me down. Because of this I always take her to classes and smile politely as The Them (as I call them) brag about their flash machines until something goes wrong and the tutor has to fix it for them. It Always happens. And my little 4030 gets another gentle stroke. I wish in fact that the Beach Boys were still around to write a song about my little machine she deserves it. I will post this question now.
