Computerized vs. mechanical...the big debate. A hotly contested one on this board. I've killed a mechanical machine so nothing is impossible. There are goods and bads with everything you decide to sew on. I "own" an electrical engineer and DD married a soon-to-be one. Electronic and computerized are not bad words in my home. We've repaired many machines (mechanical and computerized) and its a toss-up.
Everyone has a bias and will tell you their opinion. When it comes down to it, you are the one who has to decide. I like free-motion embroidery because I can't sit still long enough to let the machine do the work for me. Yes, the machine's embroidery is more perfect but to me that is a drawback.
I prefer my machine for many reasons and really don't like a fully mechanical machine. Old mechanical machines have advantages, my nephews and I disassemble them and scavenge them for robot parts at times (yes, we put them back...mostly) but I have to admit I don't like sewing on them.
