Or just go with 24fps, which plays fine on 30fps displays, uses less bandwidth (or the same bandwidth and has higher picture quality), and looks "better" due to 24fps being the frame rate of movies (and 30fps being the frame rate of straight-to-video daytime tv).
30 or 60 makes sense for fast motion, but most things people are shooting are talking heads and stuff like that, which don't really benefit from higher frame rates. 24 is good.
