It depends - did you originally pick the New Baby over the Classic based on price or appearance? If it was price, then a fuss would be much ado about nothing. If you went for the New Baby based on water reservoir access, a certain style or color, or wanting a poly housing since it is rust proof, then it might be worth a phone call. On principle alone, I would have a hard time with spending several hundred dollars and not getting what I ordered without my approval for the swap - I did not see any mention of prior communication in the original post.
