My choice years ago was Olympus (OM1 & OM2), I also dabbled with a Yashica and an old Bronica medium format camera's.
I had a darkroom with a brilliant Phillips pcs2000 enlarger and colour analyser, the most awkward part was getting the colour balance right, it took a lot of time inc washing/drying drums etc with much wasted chemicals. The best item I purchased in the later years was a deep tank processor of which totally avoided drums etc.
It was a lot of fun, but since going digital, my main interests are in studio and lighting set-ups, and digital allows much more time to do this, as well as being able to double check exposure.
Its a different world now with more effort now spent of producing printer/paper and camera profiles and getting colour correction right at the click of a button. I can now produce prints as good a standard as some of the most expensive print houses. Playing in photoshop is another part of the process to achieving the wanted end result.
I wouldn't go back to film now.
