I'm glad this thread has some sensibility going on in it and some legs to boot. I just think that enlargers, being not more than heavy duty heat resistant view cameras pointed downward have room for improvement. Until I get a proper darkroom space, I have to make do with my "Volkswagen" 45MX and my Versalab and maybe some home made tricks.
I think lightweight LED VC light sources can open up a lot of new possibilities in designing slick hybrid enlargers from the ground up. I look forward to messing with it when I have the room and cash...
If you were to design an mulit-format enlarger for black and white multigrade printing from the ground up and had a decent budget, what would you do?
