Igenity has a price break after 50 samples, if memory serves me correctly.  Keep in mind that you also have to run parentage on all of the possible sires, unless they are AI sires or your bull supplier has run parentage already and is willing to transfer the data to you.  The last two years we have tested our entire calf crop to get a handle on the bulls we are using.  It isn't cheap, but the data is fascinating.
