Wow!  Bill Duggan?!?  My photo-3d membership just increased in
value!  It is good to have some EXPERTS around here...

Are these screens still available?  What material is used in the
current Da-Lite screens?  I have a 72"x72" Da-Lite Picture King
(we use it in our club too) and I am happy with it.

Also, how about polarizing filters and glasses?  What is the
best source for those?

Thanks and regards,
