I'm located in Spokane, WA. I've transitioned away from 35mm digital to using 120 film exclusively and have sold all of my digital gear, freeing up some money for perhaps a low end digital back. Unfortunately I am unaware of anywhere nearby to demo any of the backs/systems. I know Optech in Seattle has a lot of equipment, however photography is a hobby not a job, so I can't get there for their weekday only hours. Anyone have suggestions for places to go, or live nearby with one I could examine? I'm currently shooting the 645AF system, so I'd be looking to stick with a Mamiya/Phase One system.
