I'm going to go against the grain on the topic of quality animals will keep prices up. I've seen people produce great looking pastels that are super bright from browned out ugly pastels. I agree selective breed helps refine the line, but I don't it's going to command that much more money than what the average market is going for. People are cheap. If I needed a bee and I was comparing an average looking one for $500 and a great looking bee for $750. I would buy the cheaper one and save the $250 and buy another animal, rack or have some beer money for a while.

Beauty is in the eye of the beholder. Some guys like fats chicks, others the opposite. This is just my thoughts on the subject.
