Can anyone recommend a good basketball statistics program?

Hello.

I'm looking to compile game-day stats for my team this season.

What kinds of programs are teams currently using? I'm looking for a program where I can input key stats (field goals, free throws, rebounds, steals, turnovers, fouls etc) directly into my laptop computer as the game is played - then print out a summary at the end of the game.

Shareware (free) software would be ideal but if a commercial program is the standard then I'll explore that option too.

Please send me your recommendations. Thanks in advance!
