Not 100% sure that you’ll get an eventer, but since the poster above suggested Hirentanz, I’ll also suggest his son Ehrentanz. I know him personally and he is the cuddliest and best mannered stallion I think I’ve ever been around. He’s gorgeous and very talented in the upper-level jumpers in the Midwest. I know that he has done a good amount of dressage and he did enough eventing with success to get his “Pg” designation.
He’s also had quite a few good looking babies. Sylvia is a fantastic person and will be great to work with for you and/or your vet. It also looks like he ships live, since you have a maiden and might need it.
Good luck, have fun!
