Cumberland Park, Mission Club, Camden World Gateway, and Abaco Cay are very popular among cast members. I'd avoid Burna Vista apartments behind the MK. Sabal Palms gets mixed reviews. Plantation Park exits onto an insanely busy street so I wouldn't consider it. I don't know prices, unfortunately, but they're pretty competitive. Dr Phillips is really nice and safe but might not be as cheap. Champion's Gate gets great reviews, same with Davenport. I have a lot of friends down there so if you need an opinion on a specific area, feel free to PM me and I'll see what I can find out.
Definitely get a roommate if you can. Will bring costs down significantly.
