where to get trackpoint caps?

[Paul Rubin <phr@netcom.com>]

Does anyone know where to get replacement Trackpoint caps 
these days?  There used to be an IBM 800 number where you could
order them, but I remember hearing it's been shut down.
None of the Thinkpad dealers I've asked have them available.
It's really annoying.  I'd like to have about 100 of them on
hand for when supplies dry up like this, but IBM was charging
$5 for three of them instead of 10 cents apiece or so like
they should be.
thanks
