My darkroom so far...
Three Durst condenser enlargers make light work of switching between film formats. These are wired to an RH Designs' Analyser Pro and f-stop timer. The De Vere 504 (now with Ilford MG Head) is an unplanned recent addition.
With the benefit of hindsight, I would have done one or two things differently, but hey - not bad for a first attempt.
