my workhorse is a 70s Kenmore. I keep a walking foot on my 90s plastic Sears machine (it was my first). My kids know not ever to mess with my machines without my permission.
I tell them all that I am satisfied using what I have. I have cams, if I ever decide to try to tackle some embroidery. So- so far so good. Except, I would like a larger harp for quilting.
If I *have* to replace a machine, I just might dream big! ;0))
