these are more closer to 1983-85 units......
just another example, of using the date they bought them than the actual date they were built....after all, they stopped making the filter-flos around 1997..
and that inflated repair bill is way off the scale for a valve replacement.....should be half of that.....
same goes for the price, granted a nice set, but even the asking price should be about half.....besides, a used appliance store would offer delivery/install and a warranty.....you not getting that with a private sale...
