Embryonic stem cells are rare in America because of religious types. They're not particularly difficult to manufacture or extract--the limit is really human eggs, and we can make those in the lab [1]. (Human sperm are not, for many reasons, difficult to secure.)
I'd actually guess hESCs would be the cheapest route. If we insist on iPSCs, then this turns into a personalised medicine treatment. But in that, it's no different from e.g. oncology.
