I have a Metrolux II also. Everything Michael said is true. The Metrolux II is much more timer than a Zone VI. I have used both and regardless what all the Zone VI lovers say their timer is not as good as a Metrolux II timer. You get the time that has memory with 4 channels and straight time. You get a small densitometer and a shutter checker all built in. There is a little device that will adjust your exposure up or down when you need a larger or smaller print. It is a very cool device.
