I originally posted the links to Harry Epstein in a couple of threads here and two other forums.
I managed the tools for a couple machine shops and we always used Starrett or Brown & Sharpe. Mitutoyo started becoming a big maker of quality measuring tools at lower prices followed by a bunch of others at slightly lower price and quality. Starrett started trying to compete at the mid range and did not have much luck making tools at more affordable prices. We had a lot of Starrett issues on the mid range tools but their inspection level tools never seemed to fall from stellar quality. I would rate PEC $80 12" 3 piece cast Combination Square higher than the $110 Starrett equivalent. Getting that $80 PEC as a second from HJE for $30 just makes it that much better. See it here:

I toured the PEC factory and saw they were making PEC, Fowler, and Mitutoyo in California. We bought some seconds directly from them but then made a deal with Harry Epstein for all their seconds. Most of them are simply cosmetic and the prices are mostly REALLY cheap. There does seem to be the occaisional one that is more than just cosmetic but Harry Epstein customer service is great. Most of the ones will say "PEC" but you will get the odd one that says "Fowler" or "Mitutoyo". In the past two years I have bought 50+ PEC items from Harry Epstein and the 2 that were below expectations were still good enough for the money that I kept them anyway for beginner use.
I think a Woodpecker 1281 for $90 combined with PEC 7104-4R 4" Double Square, 7105-4R 6" Double Square, 7121-006 6" Combination Square, and 7142-4R 12" 3 Piece Combination Square with center finder, & 7185-12 24" blade for another $90 TOTAL should cover a lot of different uses for a total of around $175. The cast heads will not last as long as the better hardened forged heads in the Starrett high end line but you are getting 4 different squares and an extra 24" blade for less than half the price of one Starrett 33HC square, which is almost $200. Even in daily use, the cast heads will stay accurate for a decade.
The one item that Starrett makes that I really like over PEC is the Model 61 6" double square that is larger in size, where PEC 4" & 6" Double Square are both the small size. I can't see paying $125 for the Model 61, though.
I have to say for woodworking type tasks the Woodpecker model 1281 is way more useful than a combination or double square for many uses. Incra makes similar, but non calibrated, squares that look really nice also. You just have to pick the right tool for the job.
