These will get more expensive but at least not unobtanium because of
Rochester Electronics.   They can make perhaps another 250k of them from old
wafers, and then they'll have to go into production which will probably bump
the price up, but at least they wont dissapear.  I grabbed some from
Futerlec just to have around ( I've been on a semiconductor aquisition spree
this week... ).
