I was shocked to see that horse valued at $15,000 dollars
Here in the UK I think you'd be incredibly lucky to get £4-5000 for the English equivalent ($15,000 works out at about £9,500), and as others have said, it's not a "ranch horse", it's a kid safe horse.
Over here if you go on Horse and Hound and look in the £9,000-£10,000 range, you're looking at slightly older, well proven eventers/showjumpers/dressage horses, or younger, very well bred prospects who have gone out and done a few bits and done well.
$15,000 for that? No thank you.
*edit* In all fairness, the horse market over here is terrible!
