You might want to look into the SINAR DB system if you like using that shutter, but also want some modern engineering and a bit more capability behind it. It is self cocking (with a four second recommended delay between shots), has an automatic aperture that can be preset from behind the camera, has shutter speeds selectable from behind that camera, and with the use of an additional cable, it will automatically close the shutter upon insertion of a film holder. Another big benefit is that lenses that are normally very expensive are very cheap in the DB barrel mounts. You can also put any lens with a rear element that is smaller than the shutter opening onto the camera using extended lens boards. I don't think it is the best way to use a view camera in ambient light (which is why I sold my DB shutter and lenses), but it is certainly the most convenient and the fastest. I think it is absolutely ideal for someone using flash in studio a lot.
