Mitch, the plastics store I went to said the same thing about poly-carbonate, in that it was stronger and less brittle. They would have sold me a piece of this but there was none in the scrap bin and they have a minimum cut charge of $10, plus whatever the plastic is worth I imagine so I just decided to play with the scrap bit I got, I figured it only cost $5 so couldn't go too far wrong.
And no probs with the decals for your prospective Galaxy, I will gladly print you out a set and post them to you. just PM me when you are ready.

Cheers all

Cool thanks for the offer  will definitely keep it in mind, and contact you if i end up getting it
