Here's another thing to think about. The more simple the machine, the less trouble to maintain. I've got a painter's brush that I pick up lint with. I've got magnetic bowls for my pins and a telescoping magnetic pin-picker-upper that I don't have to keep away from my machine. I don't have to worry about electrical storms. I don't leave my machine plugged in during a storm, but I don't have to panic is it was left plugged in. Many high end machines must be protected from electrical storms/
So a simple machine not only works quite well for me, I don't have to baby the thing.
