Kohler or American Standard Bathtub?

I am looking at two 30" x 60" cast iron tubs:
Kohler Villager $359
American Strandard Belmor $726 + $250 shipping
From the pictures and specs these two tubs are virtually the same.
Can anybody think of why the American Srandard costs 3 times as much?

Part of the reason is the shipping costs. The other might be that American Standard stopped making cast iron tubs years ago, so maybe they are buying this one from some other manufacturer who still makes them, (maybe Kohler).
