Just got my new 505A Protractor.  With a name like Starrett, and the $50 advertised price, I figured I could not go wrong.  Well I did.  This is a great tool but not too well built.  Oh it is heavy enough, but for the money 90 degrees should be just that, not 89.5 or 90.5 and yes, all the other angles are off by a half degree too.  I have cheap plastic protractors that are dead on.  There is no excuse for shipping these things if they are not dead on correct.  I paid for a quality protractor and got an expensive T-bevel.  Shame on you Starrett!
