Dutch Warmbloods are EXCELLENT jumpers. BUT... a good Dutch jumper can run you $60,000. They also have wonderful temperments. TB's are nice too. My friend has a beautiful Thoroughbred who is a good jumper. His name is Victor. You can see pictures of him jumping here: Click here: Webshots

I have also heard that Cleveland Bays make pretty good jumpers, especially if they are crossed with TB. Irish Drafts are natural hunters, but I haven't seen many around. Other good jumpers: Selle Francais, Holsteiner, Trakehner, and I am sure there are more.
