+1, unless you're a masochist in a big way.

By the way, other makes of roll film backs will do as well for you as Graflex or Mamiya. Note that all but early Mamiya RB/RZ backs have interlocks that you'll have to defeat, also that the lovely S-shaped backs for Mamiya Press cameras are very hard to adapt to standard Graflok backs.
