So what did you finally purchase?
After years of many different cameras I like my Deardorffs. Second choice for field work for ME would be Canham. If weight didn't matter and I wanted low cost I would get the old Calumet 'Green Monster'. Bombproof, heavy and it works forever and is very cheap on the used market.
One lens, a 300 NikkorM for low cost and good quality or a new Cooke Triple Convertible if cost were no object.
Ten holders and a changing back along with a Ries tripod, Pentax digital spot meter and you are in business. The dark cloth I can make easily using wind/waterproof cloth and microfleece so I have wind, rain and cold emergency blanket in the darkcloth... with a black side and a light gray-white side.
Add in one nice loupe to help with focus and I am ready to go.
For processing, 8x10 to 11x14 trays, Hake brush, Sandy Kings Pyrocat HD developer and a green safelight coupled to a foot switch and I can develop any B&W film by inspection and never a scratch on the film. Slow, but one at a time gives me the darkroom time to contemplate and enjoy the process as well as the image. Contact printing frame, Lodima paper(now that my Azo stock is dwindling) and I am in business.
Can put a low cost kit together like this for well under $1000 US. By shopping around and getting lucky I can put it all together for half that if I don't mind waiting and hunting for stuff.
Either way, nothing compared to a fine contact print. Get it right in camera, process and print and show fine images.
Need a source for developing by inspection and some top inspiration? Take a workshop for this type of workflow at
http://www.michaelandpaula.com as this husband and wife team are excellent. They work this way and are good teachers. Their workshop is worth every penny and then some.
Let us know what you ended up with for a working rig.
