I do not understand the pricing on Woodpeckers tools. You can see the quality and care that go into their design and manufacture, but in general, I am not willing to pay those prices. I am especially annoyed that they charge so much for aluminum, no matter how well machined and finished. I hope that Woodpeckers has a scientific explanation of why aluminum is the best possible material for their tools, other than manufacturing cost and profit margin, which must be outrageously high. Who knows, there could be a real justification for the pricing, but I don't see it.
I recently bought two items from Woodpeckers, but only because there were no alternatives that I could find. I bought a five piece carbide pen mill set, which arrived yesterday. After wearing out two of Rockler's $35 pen mills (even though I resharpen them myself) I figured that the $85 Woodpeckers set with replaceable carbide cutters was the way to go. (I may hand it to Spouse to deliver to me as a holiday gift), I also bought a tiny square as a gift for my spouse to square up blades on her scroll saw. It was the only tiny square that I trusted to fit in the small space. I had to call Woodpeckers to get the outside dimensions. It will arrive soon.
What are your precise requirements?
Inside square only? ... or inside and outside square? Not all squares are square on the outside.
Do you need measurement markings, or just a square?
Would less precise markings (say 1/8 inch apart) be sufficient? (Thinking framing/carpenter's square here.)
Must the square have a lip, or would a flat square suffice? (Again, thinking framing/carptenter's square.)
If you don't need markings, you can make your own squares. I have friends who use their own shop-made squares. Some of them are made from beautiful hardwoods with brass inlays and metal or wood blades. Others are crude, but they are square. One very old woodworker in our club uses nice shop-made hardwood squares, probably mahogany. Nothing special, just old, well used, and square. I keep thinking that I should do the same, if for no reason than skills development.
Not all fancy squares are square. I have a 9-inch Robert Sorby Gilt-Edge rosewood and brass try square that is not square. It makes me mad. I bought a similar six-inch Crown try square at Rockler, and returned it. It wasn't square either. Over the months, I noticed that the same square would disappear and reappear on the peg. (The SAME one, not a replacement; I know from an incidental mark on the plastic package.) I assume that others bought it, found it not square, and returned it. I finally made a comment about it, and they took it off the shelf as defective. I just looked at Amazon, and those same Crown try squares got terrible ratings.
