I've seen these combination squares for $35-$235. Differences? You ALWAYS pay for accuracy. I have been using General Tools for MANY years now and many things determine why I keep buying their products. Price, quality and yes, accuracy. This combo set is very useful for general marking on wood, metal, plastic etc as well as for the precision that may be required for a machining project that may require tighter tolerances.
