I don't know of a better bow in the 300$ range than the Martin Jaguar Magnum! Is it as good as a 1000$ Mathews? NO! Is a Mathews 3 times better? NO! Most bows on the market from the major manufactures are good bows!
Just don't fool yourself into believing that a high dollar bow can make up for poor shooting! If a bow is quiet and consistant, it is a good bow! From there, it is up to the person holding the bow!
