I'm not sure which brand of enlargers are available in your country, but finding a Durst may be the answer for you. Here in America, we have many models to choose from, from basic 35mm only up to 10x10 and even larger. I have an Omega D-6 with a lens turret for 3 lenses and several negative carriers for half dozen formats from 35mm through 4x5inch. I also have a Beseler 23Cii that can handle everything up to 6x9cm., and another Omega(C-700) that does the same.
