Sure, but they also have 100% het albinos, 50% het pieds. And they had some albino pos het pieds, and some pied pos het albinos... though I think they've only got males left there. Anyway, I'd be happy to buy two or three of those, especially if they had pied markers--and at those prices, it's possible to buy more than one.
But everything you said is still true. 100% double hets are worth their weight.
