I'm just a 3.0. I probably won't be hitting the WTA tour any time soon. I understand this. But I really need to find a way to practice more to groove my stokes and improve my consistency. I am thinking of buying a ball machine for this. Would this be a hopeless waste of money and an outrageous luxury for someone like me? If you own a ball machine, do you get a lot of use out of it? What should I expect to pay for something that meets my needs but doesn't greatly exceed them? I really don't want to pop a huge amount and find I have a white elephant that doesn't help me improve any more than hitting against a wall. Nor do I need a ball machine just for the sake of getting a workout or for conditioning.
