I second nsurit. You will go head over heels for the beautiful Zero Image cameras. Really, the quality and attention to detail is astounding.
My 6x9 deluxe multi-format I purchased is a joy to use, though an often brutal reminder of how darned lucky we are with modern SLRs or even MF/LF cameras: so primitive yet so successful: we're going back 600 years I think and the results achievable are quite startling against the clinically perfect and tack-sharp images we normally strive for. I don't know anybody at the moment using a Zero Image 4x5 but that may change. Some local images on Zero Image pinhole are beginning to bob up on Flickr.
