Agree on the Bronica, I own a well used (as in used by a wedding and fashion photographer) Bronica ETRS with grip and prism. PE lenses are definitely a safe bet, and they provide you with half stops as well. I own the 75mm EII and the 150mm MC (f/3.5, not the f/4 rubbish), and they are both outstanding considering I paid 150€ for both.
If you want something even bigger, you can get the Bronica GS-1, which is a 6x7 reflex in the same style as the others and, possibly, the smallest 6x7 modular reflex on the market. Any lens for the GS-1 is at PE level or above, it was the last camera Bronica ever made and it just shows in every corner.
Any of those Bronicas will last you a lifetime, they are truly workhorse in the medium format world. Hell, I even chipped a wooden floor by dropping mine once (it has been dropped multiple times by the previous owner, but has no dents).
P.S. Get as many backs as you can, because they always come in handy! Also don't lose the dark slides.
P.P.S Attached some shots with the 150mm (1, 2, 3) and 75mm (4).
