Any polarizing filter will work, just be sure to get enough that
you can twist it to the right orentation.  I don't recall which 
way the polarizers on the TI are oriented (and it probably varies
by revision anyway), but you will have to twist it around to find
the best fit.
I have tried several different filters on my calcs, and have yet
to see one not work.  Just be sure you don't get a defraction
grating instead of a polarizing lense.

I can't post to the list from this address, you might want to copy
this there if you find it useful.
