Not sure where you get the 5$ figure from?
Are you suggesting Polycarbonate in place of Alum?

Actually I did have Delrin in mind when I said that.
Had made the switch to machining with Delrin 3 months ago. Yeah - about $5 difference. Agree with its wonderful properites. Polycarb and acrylic suck for machining and long term strength.
Earlier reference to polycarb was somewhat tongue-in-cheek in reference to people always wanting clear things, despite that they may not really want the structural properties that go along with it.
