I love my Bronica ETRS. The lenses are sharp as tacks and make some pretty darn nice crisp images.
I don't know what kind of view system yours will have, if it has the waist level finder you might find it a bit odd to use at first coming from digital. But, the prism finders are easy and you should fall right into the fray without any problems.
I'd say snap shots with the digital as you learn the camera and compare the two results as well.
Have fun with the Bronica!
