Get a MB-20 handle for it, transforming the body from a F4S into a F4 vanilla. Only 4 batteries, same ergonomics, a *lot* lighter. Together with an MF-23 databack for printing shot data between frames, you'll have a superb camera. I've got two setup that way and they are used almost all the time. Pick up the handle and the back from the online place, they show up occasionally for a good price nowadays.
