Low- to mid-priced tennis ball machine models include Lobster and Wilson, with prices ranging from a few hundred to over $1,000, as of 2015. Standard tennis ball machines can cost anywhere from $1,500 to $6,000, depending on the machine's specifications and features.
Considerations when purchasing tennis ball machines include the propulsion type, oscillation feature and power source. Low-end tennis ball machines typically use air pressure propulsion, which can only generate ball speeds of up to 60 mph as opposed to machines that use spinning wheels, which can propel the ball at speeds of 70 to 80 mph.
Oscillation is a feature that allows the machine to throw the ball in random directions, something cheap machines don't usually have. Standard tennis ball machines often have rechargeable battery packs, making them easier to move around the court. Cheaper models rely on power cords.
The Lobster 201 Bucket Ball machine is one of the cheapest models of the brand. It weighs 28 pounds, has a 50-ball capacity and has a top speed of 60 mph. The cheapest Wilson model, the Portable Machine Ball is around $1,100. It weighs 38 pounds and has a 110-ball capacity. At its price range, this Wilson model already has a spinning-wheel propulsion system that can send the ball at a top speed of 70 mph.
