If they were brand new and made today with the exact same quality of the 70's, I'd pay at least $3K and use them as daily drivers.
I'm a big Maytag fan but GE would be the next down the line if I couldn't have Maytag. Lint filter, spin drain, and a nice lengthy spray rinse. It would definitely need to have a ramped agitator and 2 speed motor. I would probably end up washing most of my clothes with the slower speed agitation in a GE FF. "Regular" agitation speed is too aggressive for my tastes.
