40 year old 3.5 player getting back into the game after 20 years, slight torn rotator cuff and minor tennis elbow. Weekend warrior with 3.5-4.0 players all 40-55yr...mostly fun recreational players here, love the game and love to stay in shape. Im looking for a ball machine, under $1000. Anyone with opinions of the Tennis tutor pro lite, vs Silent Partner Star vs Lobster Freedom. Feedback like ...is 60mph sufficient, is spin necessary..etc...also size, needs to fit in a sports car, with hopper and bag.
