I’m another one who did.
I fell in love with a mare who my trainer had in for training. At the time, I had another horse and the mare was way out of my price range anyway. A couple of years later her younger brother by several years came up for sale as a yearling and after going to visit him I bought him.
Best decision I’ve ever made. Although he is still young (but now going under saddle) he is everything I’d hoped he’d be and more. In fact, he’s even nicer than the mare I originally fell in love with. I would not have bought him sight unseen but as a yearling it wasn’t as though I could ride him to see what he was like. I liked his movement and personality so I went ahead knowing I would sell if he didn’t turn out like I hoped. Fortunately, it couldn’t have turned out better!
