I am sorry your application was denied. I agree it will be faster to refile than to appeal. You should use an attorney this time. Many people try to file applications without an attorney only to waste a lot of time and money. Unfortunately, there is much more to getting an I-130/485 approved than filling out forms and providing the minimum "required" documents. Try to find an experienced immigration attorney who will not charge you too much. Good luck.
You should always consult with an experienced immigration attorney to make certain that the advice you received is appropriate for your particular immigration case.
