You might check you local pet stores, if you have any, as they often carry different dog food brands. But if this dog has been tried on other foods with bad results several times, I would be inclined to keep her on a food that agrees with her. Saying $30 is your price range severely limits your choices also. Stick with what works for her. Love and cherish her while you are lucky enough to have her. Dobermans are so very special. I order a lot from Pet Food Pharmacy as they have the best prices I have found with free shipping if your order is over $50 or something like that. Pay attention and use their promo codes. A lot of companies have special deals for first time bvyers, too.
