I have The T2i and i want to mount the H4n to use in Run-N-gun shooting format. Is there a certain somewhat cheap ($400 or less) rail/handheld system that you use to mount the H4N , Follow focus is not neccessary. Also I plan on getting a viewfinder, but may get a small lcd screen. Is there any system that would allow me to mount the H4n and the LCD ? Thanks
