I can let you know that "het" means that it carries the gene for the visual morph, but looks like a normal ball python. So, if you never plan on breeding and want the visual albinism--you're better off buying an albino straight up.

Someone correct me if I'm wrong, but baby albinos run about $1200+, right?

There are lots of reputable breeders, and I'll let someone else point you to a few

EDIT: Welcome to BP.net And good idea getting everything ready before you buy! Especially if you're going to invest in an expensive morph like an albino!
