It depends on whether you are getting the degree for the sake of the name or for the sake of a career. First: You need to be looking at grad school if you want to be a successful anthropologist. Not just because the higher certificate will help you, but more importantly; grad studies means doing research. Anthropology is all about research and that's where your future lies. You might become successful in certain areas outside the academic study of anthropology, (see Ted talk: Wade Davis) but you need a solid education. If you don't know how to look for grad school, start with this: when you come to something interesting, i.e. marriage rituals among the South Indian coasts, google that + grad school. You will get hits. Look at who the staff are. If you see someone that is in your field of interest look briefly at their publications. This shows you how much they research, or how often they are researching overseas. Then write them an e-mail telling them your interests and leave it so they can write you back. Do this with every topic you find interesting. Someone will eventually write you back. Be enthusiastic. You won't know passion in anthropology until you research and research means grad school. It's the only way unless your'e a millionaire.
