If it's for your daughter, the size and breed really isn't the thing. What counts is if it's dead broke. Many a well intentioned parent get their kid a young horse thinking they're buying a puppy. Big mistake. Forget about the purchase price. It's the least expensive part of owning a horse. Get a good horse and you won't have to find out that there is no economy in a cheap horse and an expensive hospital stay. That picture of the kid on the pony ride doesn't tell you anything. If you don't know much about horses and your putting your daughter in it, you really do need some hands-on personal help when getting a horse from somebody that understands who will be on it and their experience level.
