Hi Bill Meinze
There are different hydraulic breakers manufacturers are available, among them some of them that we can trust that they last for a longer run. Recently I have bought a hydraulic breaker of my mini excavator for demolishing the old building during the construction work. The brand which I was bought is Worky Quad recommended by my friend working in the manufacturing industry. As he is working in an industrial field he comes across different branded products. You can also consider this brand on choosing the right brand for your Cat's, a 308 and a 320.
