Around me in Lexington Kentucky I've found its $250-1, 500 depending on what barn and trainer you use. I've also found it really racks up because of the name you ride with, really.
My board is 750, the barn does everything except ride and groom your horse, automatic water and lots of shavings, half day turn out and they put boots on your horse if needed in the paddock, 3 outdoor rings, 1 indoor, 1 polo ring, and a track :)
