Rodger,
I don't know where you have received your info, but it is a bit
flawed.

I called the largest plastic supplier and fabricator in the phone book near
Portland, Maine. I'm always a bit suspicious though when I ask the girl who
answers the phone if I can talk to someone about something and she goes on
to answer the questions herself.

I take it you would go with Lexan?

Over 30 years of being involved with materials choices like this, I've often
found that "better", when applied to something like scratch resistance,
means you could detect a small difference in two alternatives used side by
side under identical circumstances but wouldn't be aware of any significant
difference otherwise. I'm trying to figure out if the scratch resistance of
these two materials falls into that catagory.
