I had a great Home Ec teacher in Battle Creek (MI), but a terrible one in Clio, so not of them all were mean.
Joe, I do NOT need any more machines so why did you show me that cute little Bernette in you second link? It's at $26 now with an equal amount for shipping. I'm sure it will skyrocket in another 40 minutes.
I think my best built machine is a 1973 Elna, but I haven't sewn on either treadle yet so I guess I'm not a good judge yet. All those Kenmores make me want to dig mine out. You're right, the plastic wonders can't hold a candle to our vintage ladies.
