It isn't illegal in America.
I really don't think that 'legal' should be the bar we are setting when it comes to buying the use of women's bodies, and the buying/selling of the resulting babies.
If you want a person who is clearly thankful and gracious and gave a heartfelt thankyou, I present Tyra Banks (who was very open about the issues she had trying to conceive):

As we thank the angel of a woman that carried our miracle baby boy for us, we pray for everyone who struggles to reach this joyous milestone]]
The woman, both appreciated and thanked, that's how the announcement is done right.
I'm still dead against commercial surrogacy - I've had 2 children, I don't think you could pay me enough to be a surrogate - I don't think I could even do it altruistically for a relative.
