IF you are planning to do a lot of outdoor shooting, be it landscape or urban locations, I'd stay away from the Calumet C-1 "Green Monster" or "Black Beast" (they made them in two flavors, with the green ones being magnesium and slightly lighter than the black ones, although there are some black ones in magnesium instead of aluminum, and I believe vice versa). I had one and shot with it in the field for a while. It is truly a beast - they're heavy and bulky and don't carry well, and most of them were used professionally for many years so they're very well worn and may be missing odds and ends and/or just loose and sloppy. If you're super handy, you can rehabilitate one, but it's a labor of love as spare parts are no longer available new, and neither are blank lensboards. A wooden Zone VI would be a much more practical choice. That, or get a Kodak 2D. The Kodak 2D doesn't have a ton of movements, but they're common and relatively inexpensive, and they weigh a fraction of what the Calumet does. Plus it will give you a chance to get your feet wet with LF without a massive investment. If you find it insufficient, you can always sell it on for about what you paid for it and upgrade to something else later.
