Subject: piece values

I'm thinking about the values of pieces for a chess program. I have investigated
some engines and the values they give to pieces vary. Some examples are:

ENGINE          knight    bishop    rook    queen
Faile 1.4.4      3.1       3.25      5       9
Amy-0.8.4        3.5       3.5       5.5     11
Crafty-19.4,     3         3         5       9
Beowulf-2.2      3.2       3.25      5       9.3   (defult personality)

I have to give values for my program and, as I'm not a strong chessplayer I
would like to know your opinion. Are these differences important? What values
should be assigned for the highest strength?. The same could be applied to score
bonuses, but the list is too large.  :-)

Thanks

Toni
