I have a bit of dexterity in my right hand (I can work the film crank on my cameras, but cannot accurately adjust shutter speeds or apertures).

A Mamiya C330 or 645 Pro with a left hand trigger grip works well for me.
Being able to focus with either the left or right focus knob probably works well for you, too.
