The judges you listed are all good judges, and are all pretty well known, so they stay busy judging a lot of big shows. One thing I would keep in mind is make sure you know your budget for a judge, some of the judges that you listed I know are quiet a haul away from you and with as busy as they stay and the distance they would have to travel it may reflect in their price. I am assuming this show is a fundraiser, so you dont want to spend to much on a judge and cut into your profits. From my experience the people that try to hire a big name judge to try and attract exhibitors are not ussually very succesful in that endeavor. The people who are going to come show are most likely going to come regardless of the judge unless they have a particular problem with a specific judge. I find that people are far more likely to decide if they are going to return to a show in following years based on show management, organization, faciilities, and prizes rather than who the judge is. I think people kind of expect the possibility of a younger lesser known judge at some of these smaller jackpots, and knowing that they know that the management cant guarantee how the judge is going to do. I have yet to hear someone say they are not going to return to a specific show just because of how one years judge did. Example, if you have a choice between a $200 judge that is going to do a decent job and a $500 judge that is really popular, I would go with the $200 judge and put more money into prizes and payouts. You are far more likely to get people to come back for the potential prizes than because of who you hired as a judge.
