What Is The Best And Most Valuable Infant Formula – We’d Like To Stay Organic.?

We can’t breastfeed and I’m astonished at all the ingredients in the infant formulas??? I’m not sure what they all are. A doctor told me that non-organic formulas are just as good as the organic ones and to use them because they are cheaper. But they sure have a longer list on ‘can’t-pronounce-ums’ in the ingredient lists.
Do you know of any good all natural/organic brands? Any great websites with deals?
