But for now I am contemplating to actually keep all my three Durst enlargers there. One 6x6, one 4x5 and one 5x7. All diffusion light source with color heads. Would there be any real benefit? Or should I at least get rid of the 6x6?
You may consider changing the 5 X 4 for a de Vere. They are the Rolls-Royce of enlargers.
