If its only 500 then I wouldn't trust it to BE a kid horse....
Ya usally kids horses are priced high because people are willing to pay good to make sure kids are safe
You can get a good deal sometimes though , if you dont know alot about horses i would take some one with you that does , there alot of tricks in the horse trading business be careful an look at alot of horses
I have drove many a mile looking for good horses
