Obsolete Equipment?

I've got some old(ish) Nikon eqpt - Nikkormat, F2AS and F3 slrs
and assorted Nikkor lenses.

Since I've moved over to digital, I've not touched my film slrs.
I'm considering buying a D70. The lenses are potential useful (though
the 1.5X factor makes a mockery of my 20mm lens),
but I'm torn over what to do with my slr bodies.

What do you guys do with your old slrs after you've switched
to dslrs? These arent exactly collectible items and so they dont fetch
much on the resale market.

It tears me apart to have to sell them but if I don't, will they go the
same way as my old Thorens turntable (which, incidentally sits
unused beside my cd player)?

Thanks for any advice.
