I was looking at SCAD's graduate program for sound design for a while. They have a great curriculum, and the school as a whole is very impressive. Few schools offer a masters program in sound design, and many schools will have a program more skewed toward music production than sound design. SCAD was certainly an exception to that. In my case, I ultimately went with a school that was a bit closer to where the jobs are, and where the instructors were still working on big-name projects, although David Stone is at the Savannah campus, and is pretty well recognized. Good luck with your decision.
