Speaking for myself, that machine, if it's in good working condition, is worth the price just for all of the working parts which could be transplanted into many Filter-Flo's all the way back to the V-12's.
If you like it, why not? I'd love to have a working FF with a mini-basket again.
I can't think what the washbasket in good condition alone would bring, but I have 5 old machines that could be much happier with a new-ish tub without lots of rust and corrosion. Also, as time marches forward, these vintage machines are getting harder and harder to find. Most of what I see on Craigslists are current POS-es that cost a lot and are not worth spit.
