Ah, did you see these on super tiny animals? I thought they were cute too, but don't be fooled by the temperament, any sheep will be tame if kept in the same sort of environment. Southdowns, ryelands, hampshires and a few more all have the cuddly teddy bear face but will be more reasonable prive to buy.
Stick to your guns if you really want some, but seriously look into the ryelands, they are not that big.
