Why penny pinch??
I was in the market for a new construction saw blade and bought a cheaper version from Amazon that stated it was compatible with my De Walt table saw that I had previously bought from ITS. When I tried the saw blade on my saw it was catching the riving knife and was 5mm larger than first quoted. With my project put on hold, I went on to ITS website and bought exactly what I needed and the job is now complete with a great finish. The moral of the story is don't try to penny pinch and buy the right tool for the job. A great saw blade that will last me another few years.
