Professional uses apart, and if the main purpose of the interest towards PC lenses is a temporary need or curiosity/fun, there are much simpler and cheaper ways to get a try. My nephew absolutely needed tilt-controlled photos for his doctorate work on the architecture of Roman temples, but could not afford one. We (his father and me) bought him an old Voigtländer plate camera with T/S controls, and he did quite fine (for his own purposes) by taking digital shots of the focusing screen.
