I try and not use my Builders Square too much. I'm too afeared I'll use up all its magic.
And in the end its somewhat of a quality of life issue. It just makes the quality of my life that much nicer and judging by the early onset of curmudgeoness I need all the nice I can get.
By the way, Woodcraft sells a 4-piece import that has the same heft as a Starrett I wouldn't hesitate to test drive one and the full set costs the same as the 2-piece Starrett. Also, almost any industrial supply house (MSC/Reid,etc.) all offer off shore squares at a lesser cost than a Starrett. They are worth consideration.
