From my point of view, they all have value. Value in what they can produce in combos and value in what they can provide as a pet for someone. While the consistent dropping in price across the whole market bothered me slightly, I have the vision to see past the first breeding season. So many people have bought up all the codoms they could find hoping to get rich. I love seeing those same people selling their collections on KS every day. Sure I paid $1000 for my first Pastel. He has already made me that much and his offspring I have kept will continue to for years. In my opinion, the market will stabilize eventually. I guess we'll have to see who is still around and who has jumped ship because they couldn't make back their money in 1 season.
As far as selective breeding, I think it's great! I love seeing guys like Albey putting up pics of some amazing animals that were produced with care and thought rather than by throwing any two animals together. But for me, they all have value...
