1.) Definately American Quarter Horse
2.) Depends on breeding, training, disposition, registration, and show background. Lowest I'd say is about $1500 highend is about $6000
3.) Here is what I see, this horse is built uphill, nice legs, ok balance cept I think the back is a bit longer then desired, I don't care for the neck looks funny to me, but then half my horses necks look funny to me :P, top line looks like it could use some strengthening. Nice Bone. Kind expression, eyes are a tad small. Neck is on the thicker side. Pretty horse!!
