I think there are several big breeders in the San Antonio area - VPI (the Barkers) and Ron Temper and Don Soderberg (South Mountain Reptiles) where all last I knew in Boerne or San Marcos or somewhere down there. On a $50 snake you could easily pay double with shipping.

Yes, the markers aren't seen in 100% of hets and are occasionally seen in non hets but they would certainly be a reassuring sight in a reported het from an unknown source.

You might be able to find a double het albino pied male from a good source from around $200 if you want one snake to do double duty and eventually work toward albino pieds. Because a female double het would be a lot more you could start out with just a het albino female and a different het pied female but then any albinos or pieds produced with the double het male would also be 50% chance het for the other. Nice extra for the $150 or so extra investment which would be made back by not having two males to feed up.
