Well... I have an amazing Spanish bred gelding out of a Multi-National Champioin imported Spanish mare, and by a National Top Five stallion. www.allbredpedigree.com/moody+baloo
This is a "been there, done that" horse. He is on the sales list now, but only until or if, other's sell first.
I'm partial to my Spanish, Russian, and Polish bred Arab's as they tend to have a lot more substance to them.
But, I guess, it depends on where you are, and how far you looking for that right horse. And what specficially (broke, age, etc) you are looking for.
Best of luck in your search!
