I have a few NOS Fidelity Research MCs. They're probably 35 years old, and every one is fine (with no special storage). So are MCs from Dynavector, Koetsu, Audioquest — but that's just a few brands, and one can't draw a sweeping conclusion from it. Van den Hul recommends storing his cartridges in your freezer! Sealed against moisture of course.
Gary, your alternative — to sell it and buy a new one in 5-10 years — presumes they'll be available; be good; and have sane prices. I wouldn't presume that.
