My preferred disposal method of anything that I think has some value is to post it "free for pickup" or if it's a real hot thing (like cut up logs from a tree felling) just put them on the grass strip between the sidewalk and the street - the universal "free" location.
I usually list it for $5. Free seems to attract too many high maintenance or scary customers.
I still think it was the right call to give it a shot. Save my uncle and myself, nobody I know will try to repair anything themselves.
