It looks like Starrett recently released a new ProSite miter saw protractor, the 505P-7. The new 7″ protractor is made from plastic and includes the same angle-finding features and laser-engraved scales as the aluminum versions.
Because it’s made from plastic, the 505P-7 is about half the price of Starrett’s aluminum miter saw protractors, at about $25.
