NYU Master's admits about 50% of applicants, and about 50% of those people attend. I think it might be beneficial attending if you think you can get some solid research experience from it. Of course, there's no cut and dry rule to it. If make good connections, improve your GRE scores, write a better letter as a result of experience, and in addition, get more experience (maybe a publication), then yes, by all means, it's a good idea. Especially so if the research is in line with your current interests. Email some profs and see if they'd be willing to take you on as a Master's student. It may be a money-maker - but it's what you make of it!
