richboyphoto, I have a Velbon 640 which accomodates my SQ-Ai and is very stable. Later acquiring a Mamiya RB67, which is much heavier than the Bronica, I tried the Velbon 640, expecting problems; but again the Velbon holds it nice and steady. I bought a Manfrotto quick release plate to use with the Velbon tripod, a bit better than the Velbon plate. If you are looking for something on the 'cheap' side then the Velbon will do. If you have money to spend then go for the dearer makes and models.
