We were faced with the same moral dilemma last week. We had a bunch of acrylic stuff lying around, but we looked in the rulebook and it is very clear that only "polycarbonate sheet" is allowed. The trade name for polycarbonate sheet is Lexan. Although it would be virtually impossible for anyone to tell the difference until it breaks, we ended up getting some lexan w/ accordance to the rules.

: "Plexiglass" is a polycarbonate plastic-GE sells it under the brand name lexan. This is different than acrylic, which may look similar but is far more brittle and thus prone to breakage. I would recomend polycarb if you plan on using it as a structural material. The acrylic will give you some troubles with drilling and especially tapping due to how brittle it is, and doesn't stand up too well to repeated bashing.
: Hope thats helpful,
