Hello /p/, help me get the greatest square frame medium format camera one can get right now, that is of course, a great deal for the buck.

Ive been flickrivering and every single image that i say OMG WOW i watch the details and its fucking always a Hass 500CM. Are these a great decision nowadays? How about a Bronica? I was very motivated to get a Pentax 67, but ive seen they are kinda heavy and bulky, even more than a Pentacon Six.

I want a 6x6 or 6x7 that i can travel with, with great image quality and that doesnt rely too much on tripods.
