That's tough to beat. $15 for an hour of hitting and they provide the balls and free court. Contrast this with lugging a machine, balls, racket, pick-up and finding a free court (and you need several as to not interfere with anyone.)
I got a machine when learning and loved it. The more I played and found hitting partners, the less and less I've used it. It is work!
