I am seriously thinking about purchasing a ball machine to use at my small and private sub-division. We have two courts that are rarely used but in great condition and with a number of benefits. Electricity and storage are available. I am interested in getting an education on ball machines and what represents good value. I would even consider used if available. Fortunately, there would be only two or three people using ths machine and I cannot imagine more than a dozen hours a week or so. Thanks for advice, in advance.
