I guess none of us really answered your question. Several of these bulls are note worth a few of them even to the point that most people don't ai to them but instead flush them. I would look up pictures and do some research on them decide if they are worth putting in your herd.
As a note a trump daughter brought high seller at Cates sale yesterday for $100,000. Granted this from a notable female line that they carefully selected for breeding and came from one of the most expensive sales in the nation.
My advice research and figure out if they fit in your breeding program and if they do use them carefully.
