Ball Machines

[FulhamFan]

I have seen ball machines reproduce every shot except for the service(unless it's underhanded). Are there any ball machines out there that spit out 120 mph serves? Is this something that there just isn't a market for?

I don't know where you can find one, but Agassi used to use one. He had one that you could adjust the height....and he would set it up to practice returning 140 mph serves - no joke.
