Yep, no arguments from me. The 538 is the wifes first machine, it will stay. The 413 will be a learning tool, then if I'm successful it will be sent down the road.
And I'm in agreement with you, I'm not gonna mess with any more machines that have plastic gears.
Which Singers are poorly designed and or have the week motors? I've probably already got one, but I'll avoid them if I know ahead of time.

PS; my wife is in her sewing area making grocery bags. Sewing up a storm with her old 538. Happy as can be.
