Boy, your kids sound like my two. Firstly, check ebay, but I am sure you already know that. Second, contact Neocate individually. I have heard of them GIVING away cases of the non-DRA/ARA kind, since it's not what they sell anymore. Lastly, try Elecare. My oldest did Neocate (before DHA was added). My 6 month old is now on Elecare and actually doing better than Neocate, because it is less constipating. They just started adding DHA to Elecare, so I don't know if it hard to find it without it or not. Good luck to you!
