That's yet another good point. I certainly won't toss them out if they
are good. I'll either clean them up and ebay them or keep 'em for
backup. I have a large selection of blocks that I've acquired over the
last few years....so a few more won't hurt.

So why replace them? If they may still be quite functional, what's
the point?
