The discussion has come back around to perspective correction with a lens and rising-front camera vs. correcting in the digital domain. I have to say that, as much as I like the elegance of the optical/geometric solution, the end result should be at least as good, done in PhotoShop or the like, and, as John Pickard pointed out, the digital camera and software might well cost less than a PC Nikkor lens alone, and certainly less than a quality view camera! You can't handle three-dimensional subjects well with either method - that's a matter of geometry - so go with the system that gives you the most features otherwise...
