I think, for the most part, Possible Hets have outlived their usefullness, kind of like the black and white 19 inch TV. Sure, it is a TV, but there are far better choices out there for almost any application.
When Pieds were $25K, Het Pieds were probably around $10K or so for a pair. Those who loved Pieds, but could not afford either of the above options, took the Possible Het route. Anyone who remembers asking, "Are they from the same clutch?" knows what I am talking about. Possible Het Pied males were affordable at around $500, but Possible Het Pied females were still about $1500 or more at one point in time. This was PH hayday, when the visuals were priced like nice new car, and Hets priced like a used car. They were a gamble, with a great payoff if you hit on them. Remember the arguements about having a better chance with a 2.3 PH group from the same clutch vs. animals from two or more clutches?
The facts are pretty obvious now, there are VERY few projects out there where a visual is $30K or so, and Hets are a third of that, meaning PH's might be a viable solution for someone without the big cash. My take, if you cannot afford a Het pair, maybe you cannot afford to get into that morph...?
PH's have a bad rap due to scammers. Some people have proven them out and swear by them. For me, PH's still have value if YOU produce your own, or if you have Possible DOUBLE Het pairs or trios. OR if you have several PH's or PDH females and a double Het or visual male. The only way I would buy a PH now, is if someone has a Spider or Pastel or name you Do Dom female that is possible het for some simple recessive gene that I have going in my projects, and the price is basically for the Co Dom animal with very little or no premium for the PH part.
