In my decision-making, I never make selling decisions based solely on genetics. They need to be solid in conformation and as close to the breed standard as possible before I will glance at the papers. If there's a doubt that a buckling should stay intact, then it's probably best that they be wethered.
The best thing to do is to research desirable conformation in the breed. Read the breed standards and try to apply them to who you're evaluating. I have a link to the SA Boer Association's conformation booklet. It has pictures to give you a nice visual. You'll eventually train your eye to spot desirable conformational traits, and it'll be much easier to determine the strengths and weaknesses in your stock. It should make your decision easier.

Additionally, check teats, scrotum, bite, and pigment. Those are easy to check and either faults or not.
