Some people like TLRs some don't. I like the one I have. Personally I like waist level finders more then prisms that SLRs tend to have. But you might not. All I can say is see if you can borrow one for a few days.
I'm not sure which Bronica model you're looking at. If it's the model with leaf shutter lenses then I think you'll find other cheaper cameras out there if you can live without the leaf shutter lenses. Plus with the focal plane cameras you can spend $30 or so on an adapter and fit the various Kiev lenses. Things like the 30mm fish eye which you might not want to spend the big bucks for from a western camera company.
