You could probably have asked the same question about Black Widow bows which I have owned for years and have found them strong, dependable, and great shooters...and there are always lots of them for sale. I just believe there are lots of Widows made and sold with many owners wanting to upgrade, try a different model, or get one with less weight.
As for the ACS, I just got a notice that my order was ready to ship also. Without doubt, the ACS makers are cranking them out a lot faster than Mr. Adcock and I am not seeing any negative comments about them either.
