The kind of focuser assist appropriate are those with a focusing screen and less the, albeit fashionable, microscope variety. Durst and Linhof had made some excellent units with built-in magnification and Paterson once upon a time had a low cost focuser with a large screen and no magnification. They tend--- even with films and formats where the grain is more clearly defined--- to be more accurate than the arial projection designs. The microscope units I think are appropriate for less than solid enlargers with glass-less negative carriers that by virtue of their construction are ill-suited to the use of focusing negatives.
