Welcome to the forum Nathan. I used to use a Bronica ETRS with a prism finder after using a waist level finder. The prism finder is easier to use because the image is the right way round. The prism finder is really great for candid shots. Most people don't believe you are actually taking a photo of them. If you can find an ETRS at a reasonable price get it. It dosen't weigh much more than a 35mm, but the image size is much bigger.
cheers
