Again high quality and beauty is in the eye of the beholder (both vendor and buyer)
Who is to say that a clown that is busy is low quality and a reduced one should be a standard and therefore quality or vice versa, trying to impose standards will not work and is ridiculous considering the variation in mutations including animals from the same clutch.
My standards are my own I would not impose them on anyone nor do I wish anyone imposing their standards on me, there is something with everything in Ball Pythons no matter what you like, people should have their OWN standards (also many do not which is why people often ask whether or not they should by a particular animal.)
If you have an animal and you think it is a quality animal you can sell it for whatever you feel it is worth if you don't believe in your animals you can give them away or sell them cheap it's up to each an everyone of us but establishing a standard and dictating prices based on that standard is just silly, and not like people have not brought up the idea over the last 10 years.
