Can I be of any help? Yes, I can but I can only relate my experiences with the enlarger etc I have used for years. A Durst M605 (for 35 mm and 2 1/4 square format) with colour head. Lenses: Nikon 50 mm and 80 mm. This configuration has never let me down. Look around on the net, they're cheap these days second hand. If you have any money to burn, spend it on an Analyser Pro (for B/W)
Good luck
