I'm a big fan of double hets. I need a het caramel male to test a few possible het females but will definitely be looking for some sort of combo and not just a het caramel.
That being said I'm surprised at how inexpensive some of the double het males have been lately. By rights they should be at least as expensive as the least expensive morph used to make them. For example, if you could have bred an albino male to your albino female but breed a pied male instead you should be able to sell your double het albino pied babies for at least as much as albinos or else there wouldn’t be much incentive to make them. However I've seen some double het albino pied males for less than albinos. Maybe it's just that the people working with double hets are wisely hording the females to help their odds and don't need the extra males.
