I paid $1500 for a male pastel about about 5 years ago as a yearling proven breeder.
Personally I do like that the prices are coming down on some of the morphs.
Though I will have to agree with many of the other people, there are a lot of morphs that I feel should not be as cheap as they are or just had the bottom fall out on them...
That said, If I had the money and it was a new exceptional morph with great genetic potential and few specimens so I knew the market would not be flooded by the time I was producing said morph I don't think there would be a limit on what I would spend.

So when I hit the Mega Millions I am going to go on an extended road trip to all the great breeders and buy all the latest, greatest, awesome morphs and combos I want and live happily ever after in my Mansion with giant warehouse out back
