I'm glad I don't have a computer on my LA! I take a lot of pride in my hand guided FMQ. To me it is art. When it is computer guided in my mind it ceases to be "art". The human element is removed and it becomes cookie cutter quilting like all the other digitized designs that look exactly like every other computer generated quilting done with the same design. There is no longer any uniqueness or individuality. Even a hand guided panto looks different because no one can perfectly stay on that line every time. But a computer can. That is JMHO. I know many feel differently and want the perfection and symmetry that can only be acheived by a computer guided set up.
Me, I would spend the 10 to 20K on other things and stick with guiding my machine myself. Every quilt makes me better at what I love to do. Why would I trade that for anything?
