TP755CD keyboard replacement

[Michael Fukatsu <mfukatsu@gauss.ee.calpoly.edu>]

The left mouse button on the keyboard to my 755CD is dying.  I don't
remember exactly when I bought it but I don't have the reciept anyways.  I
think the model is older than three years old (am I wrong?) so I can't send
it in to eazyserv.  Has anyone replaced one of these keyboards themselves?
I figure one must cost about $99 or so.  Can someone point me to where I
can buy one if I need to do it myself?

Thanks,
-Mike
