I have the industrial model but not the square.
In a prior thread I noted that I am able to align my SawStop to within .0005 of an inch in all measured directions. Personally, I am glad I have it.
I too would like to purchase a set of his squares, however, Ed Bennett stopped responding to emails about a year ago. I have called at least three times and written at least as many emails. Silence... [sad] I have considered an offering by WoodPecker ???, since I think they have a set of angled squares but their, reputed, tolerances are not close to what Ed offered. I hope what you returned was not from WoodPecker.
You best bet for acquiring one is to watch eBay, Craig's List and other WW boards. I know they are out there and eventually someone will want to sell theirs; that is how I acquired mine.
Good luck.
