PBR is good around here. Not only do they do official measurables, but they take film of the player fielding balls, at the plate, pitching, etc.. Tends to be reasonably priced. Video can be exported to schools.
The only issue around here, is that the workouts are almost always on turf, and not always the best turf. It sort of homogenizes the fielding, making the bad ones look better than they are, and the good ones more ordinary. Also can be a bit funky for getting a good 60. My eldest always runs faster on grass, and in competition with another runner(PBR is solo)...never ran under 7.0 at a PBR event, but ran 6.8-6.9 at other legit events.
Minor quibbles, though. Pro outfit, no BS. Relatively inexpensive. Son had to get wisdom teeth removed, causing a last minute cancellation, and they refunded money w/o a hassle.
